Answer:

a. None of the answers given is correct

Explanation:

Nitrogenous bases such as uracil (2, 4-dioxy pyrimidine), thymine (2, 4-dioxy-5-methyl pyrimidine) and cytosine (2-oxy-4-amino pyrimidine) are pyrimidines. Cytosine and thymine are found in the DNA but in the RNA, thymine is replaced by uracil.

The pyrimidine undergoes catabolism through ring cleavage. The end products of catabolism are beta-amino acids, ammonia and carbon dioxide.

Explanation:

The process of evolution explains how closely one organism is to another based on their common ancestors. Scientists believe that those organisms which show many similarities in their structures or functions might have evolved from a common ancestor in the past.

As in the above-mentioned question, scientists have observed that cetaceans lack gills and breath air, this is a property of land mammals. The cetaceans have fin bones which are similar to the limb bones. As limb bones are present in land mammals, hence they cetaceans and land mammals might have common ancestors in the past.

dlinn [17]
Scientists who do this are doing what is considered to be and called cloning. Cloning is exactly this - taking cells from one organism and trying to produce and recreate an identical (from a genetic perspective) organism.

This can be done in a routinely fashion but there are serious ethical considerations nowadays.
