Module 8 Flashcards
1
Q
Describe how STRs could be removed from a sample of DNA. (2)
A
- restriction endonucleases
- cut DNA at specific base sequences
2
Q
Genetic fingerprinting using STRs requires amplification of the STRs using the polymerase chain reaction (PCR). The short base sequences either side of a specific STR are known.
Explain the importance of knowing these base sequences in PCR. (2)
A
- to produce primers
- to produce a complementary base sequence
