Q

What is the best way to determine of a person has a single nucleotide polymorphism?

A

perform an RFLP analysis

17
Q

SNPs (single nucleotide polymorphism) are becoming important in forensic science because

A
  • they are useful in degraded samples
  • smaller fragments are needed than for STRs
  • of their low mutation rate
  • because they are common in DNA
