what is cloning all about?

Introduction\nThe possibility of human cloning, raised when Scottish scientists at Roslin Institute created the much-celebrated sheep "Dolly" (Nature 385, 810-13, 1997), aroused worldwide interest and concern because of its scientific and ethical implications. The feat, cited by Science magazine as the breakthrough of 1997, also generated uncertainty over the meaning of "cloning" --an umbrella term traditionally used by scientists to describe different processes for duplicating biological material. \n\n\nWhat is cloning? Are there different types of cloning?\nWhen the media report on cloning in the news, they are usually talking about only one type called reproductive cloning. There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to taking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies will be discussed: (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning. \n\n\nRecombinant DNA Technology or DNA Cloning \n\nThe terms "recombinant DNA technology," "DNA cloning," "molecular cloning,"or "gene cloning" all refer to the same process: the transfer of a DNA fragment of interest from one organism to a self-replicating genetic element such as a bacterial plasmid. The DNA of interest can then be propagated in a foreign host cell. This technology has been around since the 1970s, and it has become a common practice in molecular biology labs today. \n\nScientists studying a particular gene often use bacterial plasmids to generate multiple copies of the same gene. Plasmids are self-replicating extra-chromosomal circular DNA molecules, distinct from the normal bacterial genome (see image to the right). Plasmids and other types of cloning vectors are used by Human Genome Project researchers to copy genes and other pieces of chromosomes to generate enough identical material for further study. \n\nTo "clone a gene," a DNA fragment containing the gene of interest is isolated from chromosomal DNA using restriction enzymes and then united with a plasmid that has been cut with the same restriction enzymes. When the fragment of chromosomal DNA is joined with its cloning vector in the lab, it is called a "recombinant DNA molecule." Following introduction into suitable host cells, the recombinant DNA can then be reproduced along with the host cell DNA. See a diagram depicting this process. \n\nPlasmids can carry up to 20,000 bp of foreign DNA. Besides bacterial plasmids, some other cloning vectors include viruses, bacteria artificial chromosomes (BACs), and yeast artificial chromosomes (YACs). Cosmids are artificially constructed cloning vectors that carry up to 45 kb of foreign DNA and can be packaged in lambda phage particles for infection into E. coli cells. BACs utilize the naturally occurring F-factor plasmid found in E. coli to carry 100 to 300 kb DNA inserts. A YAC is a functional chromosome derived from yeast that can carry up to 1 MB of foreign DNA. Bacteria are most often used as the host cells for recombinant DNA molecules, but yeast and mammalian cells also are used.\n\n\nReproductive Cloning\n\nCelebrity Sheep Has Died at Age 6\n\nDolly, the first mammal to be cloned from adult DNA, was put down by lethal injection Feb. 14, 2003. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis. Although most Finn Dorset sheep live to be 11 to 12 years of age, postmortem examination of Dolly seemed to indicate that, other than her cancer and arthritis, she appeared to be quite normal. The unnamed sheep from which Dolly was cloned had died several years prior to her creation. Dolly was a mother to six lambs, bred the old-fashion

You guys think of cloning just like multiplying oneself! That is not how you should go about it. Cloning does not necessarily mean cloning a genome. Do you know that transforming a gene into a bacterium and having it divide in two is cloning on its own? One should ask whether people think therapeutic cloning is ethical or not! In that case, I think it is the only way out to saving someone's life very fast. If someone needs an organ transplant, there has to be a match of molecules called Major Histocompatibility Complex  (MHC) molecules. And that is hard to find. So therapeutic cloning can save the energy of looking for a match and more importantly reduce the risk of autoimmune responses during after transplant.

To answer this properly, we would really have to define what is meant by cloning. To clone something is just to make a copy, and genes are cloned safely all the time. I think you mean making an individual who is a genetic copy of another individual.\n\nThis certainly hasn't been done often, and is in no way safe. Dolly the sheep died young and had problems, and I don't think it's completely understood yet why. There was a dog cloned in Korea, but now that researcher has been fired for publishing fraudulent data, even though they've checked out the dog and he does seem to be an actually clone. It still casts some doubt.\n\nThe idea of cloning humans is completely unethical at this point, because it is unsafe. At the current state of technology, you couldn't clone a human without producing probably hundreds of babies with birth defects in the process.\n\nHow long until it is safe? There's really no way to tell. If people were determined to do this (not sure why, there are much easier ways to have children), being able to do it safely will depend on discoveries that haven't been made yet, so there's really no way to predict. Could be 50 years, could be ten years if something really amazing happens in the meanwhile.

It is a process by which a plasmid is used to import recombinant DNA into a host cell for cloning.  Differnet companies have developed their own exclusive means to accomplish this task for the reasons listed below.\n\nMany diseases are caused by gene alterations. Our understanding of genetic diseases was greatly increased by information gained from DNA cloning. In DNA cloning, a DNA fragment that contains a gene of interest is inserted into a cloning vector or plasmid.\n\nThe plasmid carrying genes for antibiotic resistance, and a DNA strand, which contains the gene of interest, are both cut with the same restriction endonuclease. The plasmid is opened up and the gene is freed from its parent DNA strand. They have complementary "sticky ends." The opened plasmid and the freed gene are mixed with DNA ligase, which reforms the two pieces as recombinant DNA.\n\nPlasmids + copies of the DNA fragment produce quantities of recombinant DNA.\n\nThis recombinant DNA stew is allowed to transform a bacterial culture, which is then exposed to antibiotics. All the cells except those which have been encoded by the plasmid DNA recombinant are killed, leaving a cell culture containing the desired recombinant DNA.\n\nDNA cloning allows a copy of any specific part of a DNA (or RNA) sequence to be selected among many others and produced in an unlimited amount. This technique is the first stage of most of the genetic engineering experiments: production of DNA libraries, PCR, DNA sequencing, et al.

Everything you need to know about stems cells can be found on this page:\n\nhttp://stemcells.nih.gov/info/basics/basics4.asp\n\nCloning is creating a viable embryo that is an exact genetic copy of another animal (or plant?).  In animals, cloning is usually done by harvesting unfertilized eggs from a female, extracting the DNA from an egg, and inserting the extracted DNA into another egg to substitute for fertilization.  Cells other than eggs may also be used, but eggs are easiest to work with.

I don't think it is as much bad, as it is unnecessary. A clone is a different person than the original. It would have a different personality and different memories and a different life. Who would want a look alike running around. The only purpose in a clone would be to farm body parts and that is WRONG.

Mostly fiction. When cloning technologies advance, humans eventualy will be able to be cloned, but not the way they show it on "the 6th say" - we won't be able to take a human body "template", "clone" it in the matter of minutes and install previous memories of the cloned individual. Normal scientific cloning, as we know it today, would generate a zygote, which would need to be implanted in a uterus and grow as a fetus. The newborn baby would have the same DNA as the cloned individual, so it would be an identical twin in a sense, but it will need to grow as a normal child to become an adult. The clone will have its own memories and probably a different personality, since it will be raised in a different environment than the DNA donor.

Cloning seems like a bad idea.  There is the whole degradation of the genes thing and all of those ethical questions.  Besides if you have clones they have to be fed, clothed and sheltered.  What I want is a small platoon of robots.  I'll get them three jobs apiece and do whatever I want while I collect their pay checks.

The purpose of a question like this is for YOU to take what YOU know about cloning (and for YOU to do research about it) and then for YOU to extrapolate from what YOU know to what YOU think might happen.\n\nTry watching (or reading) The Island. Just one grim outlook of many about cloning.

This question DOES have an answer. The answer is that since souls do not exist, no soul would be entering another's body. When, yes WHEN, a human is cloned (unfortunately someone WILL do it), the clone will have the same genes. They will look alike and theirs traits that are determined by genetics and not environment will likely be the same as well. However, they will still be two different human beings. Both are still alive and the clone will be a baby. You won't feel any different. Why would you? There are many ethical implications involved with cloning. It would be sort of like identical twins (who share same DNA and fingerprints etc) but the result would be very odd indeed especially if the two talked to one another. How alike would they be?

You should use your own opinion. My personal opinion on the matter though is that cloning does not necessarily mean actually producing another one of yourself. Therapeutic cloning is the act of making a cloned embryo and extracting its stem cells before they even differentiate. The use of these stem cells in research is very valuable and has the potential to save millions of lives around the world (for reasons I opt not to get into).\n\nThus, I believe therapeutic cloning should be legal. The reproductive cloning of humans however, should remain illegal. Basically, the creation of formed embryos should be allowed, but it should be illegal to implant them so that can develop into human beings.\n\nThat's my personal point of view though. This is a highly controversial subject and you really need to research it and form an opinion of your own.

I would guess that it would be in the field of biochemistry. Perhaps cloning will be the next big thing, where we may be able to growth individual organs for transplants.

It is entirely possible, however we are more than just the product of our genetic code, the clone would be a completely different individual. But although it possible, it is illegal to experiment with cloning of human beings. However, it is a matter of time before someone breaks that law if they have not done so already. Then again maybe they have done it in a country like China that in most instances would ignore international law.

I'm not a Raelien, but I hadn't heard about them until your post. Very interesting. According to the website the cloning is actually from a different group called Cloneaid, but the head of clonaid is a Raelien. Couldn't find anything on how close they are to their goal. I've posted some links for more info below.

Cloning is part of molecular biology\n\nThus the term "molecular biologist" would be good enough though there are scientists in overlapping disciplines, with different titles who also do cloning e.g some biochemists and (bio)chemical engineers, MDs, of course geneticists etc.

It is where they take the genetic structure of one cow's DNA and making the exact same cow. Basically they take DNA from one cow and insert it into a cows embryo - then that cow gives birth to a cow with the same genetic structure as the one they took the DNA from. Creating a clone. \n\nGo to this website for a less confusing explanation :)\nwww.ornl.gov/sci/techresources/Human_Genome/elsi/cloning.shtml
