mtDNA is used when other forms of DNA analysis are not possible because it does not rely on nuclear DNA.

mtDNA may also be useful in missing-person cases.

PCR analysis allows a small amount of DNA to be duplicated into a testing amount.

Y chromosome analysis examines genetic markers that are passed from father to son.

All four apply.

- ✓ mtDNA is used when other forms of DNA analysis are not possible because it does not rely on nuclear DNA. (True — mtDNA is separate from nuclear DNA and useful when nuclear DNA is degraded or scarce.)
- ✓ mtDNA may also be useful in missing-person cases. (True — it can be matched through maternal relatives.)
- ✓ PCR analysis allows a small amount of DNA to be duplicated into a testing amount. (True — PCR amplifies tiny DNA quantities for analysis.)
- ✓ Y chromosome analysis examines genetic markers that are passed from father to son. (True — Y-STRs follow the paternal line.)
