Question

Quizplus · Accepted Answer

A genetic marker is a region of DNA that varies between individuals and can be used to identify and differentiate between them. This can be useful in applications such as forensic science or paternity testing.

B) short tandem repeat (STR) is also correct as it is a specific type of genetic marker consisting of repeated sequences of DNA that vary in length between individuals.

C) sticky end and D) restriction fragment are both incorrect as they refer to molecular biology techniques such as DNA sequencing and cloning, rather than genetic variation between individuals.
