Animal Cloning

Describe it: Animal Cloning is the process by which an entire organism is reproduced from a single cell taken from the parent organism and in a genetically identical manner. This means the cloned animal is an exact duplicate in every way of its parent; it has the same exact DNA.

Analyze it: Scientists having been trying to clone animals for a long time. They first cloned a tadpole. It did not live but it was a big break through. Then some scientists cloned Dolly the sheep and she lived and went on to reproduce. First cloning was done by nuclear transfer and they did not live. Cloning was then done by nuclear transfer on embryonic cells and they did not live either. Dolly the sheep was developed from a developed mammary gland taken from a full-grown sheep. Sense scientists have been successful they have cloned rats, cats, horses, bullocks, pigs, deer and more. You can even clone humans now!

Apply it: One thing that animal cloning is used for is if an animal is going extinct then we can make more of the animal so that it isn't anymore. Reproductive cloning can be used to reproduce animals with special qualities. 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 diseases such as Alzheimer's or Parkinson's.

Synthesis: Cloning reminds me of twins. Twins don't have exactly the same DNA but it is close and they often times look the same. When animals are cloned it is like them having a twin only the twin is not born the same time as you. It could be born a couple years later.

Argument: I think that cloning is a good thing because it could be used for many good things. Such as animals that are going extinct, we could make more of them and then they would not be any more. Also in humans, if someone is dying because of a failing liver or something, we could clone someones healthy liver and replace the bad one with that good one.
