What is cloning? Are there different types of cloning?
_____71____ Actually, there are different technologies which can be used for other purpose besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to talking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies are usually performed; recombinant DNA technology or DNA cloning, reproductive cloning, and therapeutic cloning.
___72_____
Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. ___73_____ Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs, cats, rabbits, and a gaur. ____74____
Hundreds of cloned animals exist today, but the number of different species is limited. ____75____ Some species may be more resistant to somatic cell nuclear transfer than others. The process of stripping the nucleus from an egg cell and replacing it with the nucleus of a donor cell is a traumatic one, and improvements in cloning technologies may be needed before many species can be cloned successfully.
A.What animals have been cloned?
B.All these clones were created using nuclear transfer technology
C.When the media report on cloning in the news, they are usually talking about only one type called reproductive cloning.
D.Recently Chinese scientists have also successfully cloned mammals such as an ox.
E.Cloning is making a genetic copy of something else.
F.Attempts at cloning certain species such as monkeys, chickens, horses, and dogs, have been unsuccessful.
G.Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells.

Increased food security for growing populations
If the low success rates can be improved (Dolly was only one success out of 276 tries),reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities.For example,drug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.
Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed.In 2001,the first clone of an endangered wild animal was born,a wild ox called a gaur.The young gaur died from an infection about 48 hours after its birth.In 2001,scientists in Italy reported the successful cloning of a healthy baby mouflon,an endangered wild sheep.The cloned mouflon is living at a wildlife center in Sardinia.Other endangered species that are potential candidates for cloning include the African bongo antelope,the Sumatran tiger,and the giant panda.Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.
Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's.Much work still needs to be done before therapeutic cloning can become a realistic option for the treatment of disorders.

There are two lines of thought in the research of human cloning.The two line of thought are at the extreme ends,you either agreed to proceed with the research and clone human or you totally against the research.
For those who support human cloning,the reason is that we can get more itelligent human to be clonned.More intelligent human means more discoveries and inventions.cloning more hard working worker also get higher productivity.
Other the other hand,the people against cloning are usually from the religious group.They believe cloning is against nature or God's will
I personally support the research in human cloning.I am happy if another Skilldo is being cloned.I can take a 12-hour shift work with the cloned Skilldo to help students in BaiduYixia.Isn't it a good idea?

Nowadays,cloning is a topic which causes intense debates among scientists and ordinary members of the society.Obviously,cloning isn’t a term from the fiction novel any more but a reality we have to meet and react accordingly.
It seems to me that we should stop using cloning any longer because we may suffer emotional risks from cloning.Suppose a child grows up knowing her mother is her sister,her grandmother is her mother,what kind of pressures will he or she feel,knowing they were made as a direct replacement for another?It is a human experiment doomed to failure because the child will not be identical in every way,despite the hopes of the parents.It will place great pressures on the emotional development of the child.
Another element that plays a vital role in against cloning is that it threatens human being’s health.If scientists could transfer human genes into animals and vice-versa,diseases may be transmitted from animals to humans.It can create a worldwide catastrophe that no one would be able to stop.

Ethical issues of human cloning
Roman Catholicism and many conservative Christian groups have opposed human cloning and the cloning of human embryos,believing that a human life begins the moment a human egg becomes fertilized.Other Christian denominations such as the United Church of Christ do not believe a fertilized egg constitutes a living being,but still they oppose the cloning of embryonic cells.The World Council of Churches,representing nearly 400 denominations worldwide,opposed cloning of both human embryos and whole humans in February 2006.The United Methodist Church opposed research and reproductive cloning in May 2000 and again in May 2004.
Libertarian views on the subject suggest that the federal government of the United States does not have the power to regulate cloning,as it is not given any such authority by the US constitution.(Similar to abortion rights.)
At present,the main objection to human cloning is that the cloned individual may be biologically damaged,due to the inherent unreliability of its origin researchers currently are unable to safely and reliably clone non-human primates.
However,many believe that as cloning research and methods improve,concerns of safety and reliability will no longer be an issue.However,it must be pointed out that this has yet to occur,and may never occur.Rudolph Jaenisch,a professor at Harvard,has pointed out that we have become more efficient at producing clones which are still defective (Development Dynamics.Volume 235,pages 2460-2469.2006).Other arguments against cloning come from various religious orders (believing cloning violates God's will or the natural order of life),and a general discomfort some have with the idea of meddling with the creation and basic function of life.This unease often manifests itself in contemporary novels,movies,and popular culture,much like numerous other scientific discoveries and inventions before.Various fictional scenarios portray clones being unhappy,soulless,or unable to integrate into society.Furthermore,clones are often depicted not as unique individuals but as spare parts,providing organs for the clone's original (or any non-clone that requires replacement organs).
Needless to say,cloning is a poignant and important topic,reflected by its frequent discussion and debate among politicians,scientists,the media,religions,and the general public.
Cloning extinct and endangered species
Cloning,or more precisely,the reconstruction of functional DNA from extinct species has,for decades,been a dream of some scientists.The possible implications of this were dramatized in the best-selling novel by Michael Crichton and high budget Hollywood thriller Jurassic Park.In real life,one of the most anticipated targets for cloning was once the Woolly mammoth,but attempts to extract DNA from frozen mammoths have been unsuccessful,though a joint Russo-Japanese team is currently working toward this goal.
In 2000,a cow named dendi Bessie gave birth to a cloned Asian gaur,an endangered species,but the calf died after two days.In 2003,a banteng was successfully cloned,followed by three African wildcats from a thawed frozen embryo.These successes provided hope that similar techniques (using surrogate mothers of another species) might be used to clone extinct species.Anticipating this possibility,tissue samples from the last bucardo (Pyrenean Ibex) were frozen immediately after it died.Researchers are also considering cloning endangered species such as the giant panda,ocelot,and cheetah.

How can cloning technologies be used?
Recombinant DNA technology is important for learning about other related technologies,such as gene therapy,genetic engineering of organisms,and sequencing genomes.Gene therapy can be used to treat certain genetic conditions by introducing virus vectors that carry corrected copies of faulty genes into the cells of a host organism.Genes from different organisms that improve taste and nutritional value or provide resistance to particular types of disease can be used to genetically engineer food crops.
Benefits
Crops
Enhanced taste and quality
Reduced maturation time
Increased nutrients,yields,and stress tolerance
Improved resistance to disease,pests,and herbicides
New products and growing techniques
Animals
Increased resistance,productivity,hardiness,and feed efficiency
Better yields of meat,eggs,and milk
Improved animal health and diagnostic methods
Environment
"Friendly" bioherbicides and bioinsecticides
Conservation of soil,water,and energy
Bioprocessing for forestry products
Better natural waste management
More efficient processing
Society
Increased food security for growing populations
If the low success rates can be improved (Dolly was only one success out of 276 tries),reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities.For example,drug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.

What Is Cloning Good for?
Dolly's cloners say they were not trying to invent a way to make human clones.The goal of their research is to help farmers.
If a sheep had wonderfully thick wool,a farmer would want an identical one,or several.A cow that produced a lot of milk?Same
thing.Now farmers match up a male and a female animal with such traits,hoping that their children will have the traits too.
Cloning would be a faster,more direct way to get that result.
Some scientists say that dealing with Mother Nature in this way is just too dangerous.One danger,admits the head researcher on
the Dolly project,is that if an animal had a gene for somethingbad,such as a terrible disease,all its clones would have the same
defect.

Firstly, I want to explain what is clone. In the dictionary, clone is a group of plants or organisms produced asexually from one ancestor. It can replicate the gene from the best biology. So it brings us its usages. I think clone technology can help man to keep biology from being extinct. Even if there is an only existence of some species, we also can let this species goes on in the world. At the same time, man can get a great much of benefit from it. If somebody lost his arm or leg, we can replicate the new one by him gene. So there is no physical rejection. We will greatly help the disable to improve their life and reduce us cost in health-care.

what is your opinion of cloning human beings
虎哥无敌1年前2
笨笨厌厌 共回答了20个问题 | 采纳率85%
Opinion 1.
At this point in time I would tend to be against human cloning,but only because we haven't sufficiently developed the technology yet,and the clone is likely to have a lot of genetic defects (which can lead to genetic diseases and/or other health issues) and shortened telomeres (which would result in premature aging).
However once the technology has matured,I see no reason to prohibit or ban it.A clone would be just like any other human.It would be like having an identical twin,that just happened to be born a few decades after you were.:-) It should be noted that a lot of a person's personality,beliefs,outlook,etc.are the result of the experiences they have and the environment they grow up in.So a clone may be somewhat similar to the original in terms of personality and beliefs,but their unique experiences growing up would ensure that they would differ on a number of traits.Mentally,they would _not_ be identical to the original.Which then begs the question,what would be the purpose in creating a clone of yourself?
There is possibly one use I could think of (besides vanity).And that would be as a source for replacement organs.Obviously for this to be in any way remotely ethical,you'd have to find a way to create the clone without a brain--a body with no trace of personhood.Even then though,by the time we've gotten human cloning down pat,we should also be able to clone (or construct) individual organs.So there's not all that much use for human cloning,aside from maybe research purposes.But again,I don't think that's a reason to ban it.Our lives are full of useless tech,what's a little more?
opinion 2:
IF there were a way to clone people with no negative health effects for either the person OR the clone,and there were a reasonable reason to clone people,and the clones would be treated with the same rights as any human,THEN i would say it would be ok.If a person were correctly cloned then it would safe to assume the brain would be the same,so the clone would have human emotions/thoughts.It would be very impotent that the clone be treated as any human so that no pain would be caused,because they would be aware,Intelligent living people.
opinion 3:
Are you drawing distinction between human Cloning and Genetic engineering?
because Genetic Engineering would allow us to irradiate every type of genetic disease and defect
but for cloning the present time I would say no,currently not enough is understood about genetics to make it safe,but in the future when we completely understand the implications of what we are doing then yes God may have made us all unique but whoever said that was the best way to be?with cloning you could destroy all of humanities bad faults and come up with a completely efficient society,but you would need a higher authority to choose what those required qualities would be and for the first couple of generations that would be a very hard thing to deal with
三个观点可任选一个.

I think cloning human being is accepted but not encouraged.For example,we could clone a great scientist to continue his contribution to the world.However,modern technology could not ensure a successful cloning of human beings yet.Maybe in the near future,we could abolish the ban of cloning human beings.

你说的是不是一篇关于宠物克隆的阅读理解里的句子啊?
(...It’s difficult to deal with.It’s hard to accept.”
But would cloning reduce the blow?This question seems to be at the heart of this problem)
如果是,那这句话的意思就是
“克隆能够降低宠物逝去对主人造成的打击吗”

因为克隆cloning是无性繁殖,只是复制父本或母本的基因链,所以只是双亲之一,不需要用有性繁殖的双亲(parents)),这在汉语中较难表达.
现在一般的single-parent family都表述为单亲家庭,就是这样的例子,还有“亲子 .”也是相似的解决方案
