Question

This is a biochemical process used for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, in any DNA molecule. By comparing the DNA sequence of two organisms, scientists can see if the organisms are related or not, as well as how closely they are related.

Answer 2

Answer: Southern blot

Step-by-step explanation:

The techniques of Southern blotting helps to identify specific sequences of DNA among two or more samples that have been collected from organisms to be investigated.

This biochemical process also involves electrophoresis and hybridization of DNA to obtain the right order of the nucleotide bases, as similar order of bases would infer COMMON ANCESTRY between the two organisms.
