Explanation / Answer

12. C. Greater certainty when matching crime scene DNA with suspect DNA

13. C. RT-PCR

Real time PCR is used to identify the presence of a different species in tuna.

14. C. To derive family ancestries

Mitochondrial DNA is maternally inherited and thus can be used to establish family ancestry

15. C. VNTR

VNTR is used to establish family relations and DNA identification. Short tandem repeats were used in this case.
