Microsatellite DNA — used in which case
Question
'Microsatellite DNA' is used in the case of which one of the following?
Options
Studying the evolutionary relationships among various species of fauna
Stimulating 'stem cells' to transform into diverse functional tissues
Promoting clonal propagation of horticultural plants
Assessing the efficacy of drugs by conducting series of drug trials in a population
Explanation
Microsatellite DNA consists of short, highly variable repeating sequences in the genome. Because these sequences mutate rapidly and differ greatly between individuals and populations, they are the standard genetic markers used for DNA profiling, paternity testing, and mapping the evolutionary relationships and genetic diversity among species.
