After Dolly the sheep, it seemed that it was no possible to clone all sorts of animals. The process of obtaining a single working nucleus from any cell, put it in a embryonic cell without a nucleus, and create an entire animal is somatic cloning. Woolly mammoths went extinct four thousand years ago. Their frozen bodies have well preserved tissue and hair which made believing that finding a working cellular nucleus would be easy. This potentially could make it possible to clone a wooly mammoth. In order to see if you have a working nucleus with an entire mammoth genome, you need a map of the entire genome. The University of Pennsylvania has made major progress in doing this (Landers). Scientists are pursing cloning to broaden the understanding

No other replication supported those results. Freezing slows the process of enzymatic break down, but does not stop it. Radiation can also damage DNA in frozen tissue (Landers). At Harvard, they hope to identify mammoth genes for adaption to cold weather and insert them into elephant nuclei in hopes of creating a mammoth instead of cloning one. By reconstructing the mammoth genome, scientists can genetically engineer a cell nucleus using bits and pieces found in different viable cellular matter, and use it in somatic cloning. No single cell has yet to complete a genome making this task almost impossible. The best DNA to find on a frozen mammoth is from a hair cell that is protected by a coating. Putting a artificially reconstructed genome into a cell for cloning has never been done, but is very possible due to the similarity in elephants and mammoths. If the genome is created it would need around twenty captive female Asian elephants to be surrogate mothers and would still not guarantee a mammoth birth (Landers). The possibility of bringing back extinct animals to restore ecological system is enough to keep cloning research …show more content…
In 2001 scientists have created a viable clone of the European mouflon, and endangered species. This was done in Italy and the European mouflon’s original habitat is the Mediterranean islands. The animal nearly became extinct a hundred years ago. Conservationists debated over the ethics of cloning but saw the rewards of rescuing populations of endangered and threatened species (Trivedi). Scientists that support cloning believe that cellular samples of endangered species with somewhat high numbers should be collected to ensure genetic diversity conserved. The opposition believes that cloning is the easy way out when there should be more efforts to preserve these animals. Any tool for saving endangered species is necessary whether it may be preservation of habitat or cloning. If cloning is managed properly than it could secure the genetic material of those animals who were infertile or died early. The European mouflon is unique because it used the DNA of a mouflon, but a not endangered, domestic surrogate mother (Trivedi). Cloning of domestic species allow for the fine- tuning of techniques that can be used on endangered and extinct
