Q. Microsatellite DNA’ is used in the case of which one of the following?

[A] Studying evolutionary relationships among various species of fauna

[B] Stimulating stem cells transform into diverse functional tissues

[C] Promoting clonal propagation of horticultural plant

[D] Assessing the efficacy of drugs by conducting series of drug trials in a population

Answer: A

Notes:

Exp) Option a is the correct answer.

Microsatellite DNA, also known as short tandem repeats (STRs), is a type of genetic marker that consists of repeating sequences of DNA. It is commonly used in genetic studies, including population genetics and phylogenetic analysis, to study relationships among different species of fauna.

Microsatellites are highly polymorphic and vary in length due to differences in the number of repeat units. By analyzing the variations in microsatellite DNA sequences among individuals or populations, researchers can assess genetic diversity, population structure, and evolutionary relationships within and between species.
