Woolly mammoths have been extinct for about 10,000 years, but we occasionally find one that has been preserved in siberian permafrost. resurrecting these huge elephantlike mammals may be possible by cloning dna isolated from such frozen remains. researchers are now studying the dna of a remarkably intact baby mammoth recently discovered frozen in a siberian swamp. what are some of the pros and cons, both technical and ethical, of cloning an extinct animal?

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.

your answer is going to be physical weathering
