Attempt This Question
Not attemptedCorrect Answer: (a) Studying the evolutionary relationships among various species of fauna
Microsatellite DNA (short-tandem repeats of 2-6 base pairs) mutates rapidly, so the number of repeats differs between populations and species; this makes it a standard genetic marker for population genetics and phylogenetic/evolutionary studies. It is not used for inducing stem-cell differentiation, plant tissue culture, or drug-trial analytics. ([aashah.com](https://www.aashah.com/pyqp-st-biotechnology/?utm_source=openai))
