List two advantages STRs have over restriction fragment length polymorphisms (RFLP).

Question

What will be an ideal response?

Answer 1

The shorter DNA strands found in STRs are likely to be more stable and less subject to degradation brought about by adverse environmental conditions than the long RFLP strands. Another distinct advantage is that STRs can be amplified by PCR, thus overcoming the limited-sample-size problem often associated with crime scene evidence. Amplification of STRs by PCR allows forensic analysts to characterize small quantities of DNA.
