Question

Forensic scientists can match missing persons and their families by matching maternal DNA to the missing individual. Which type of DNA technology is used for this purpose? a) Y-chromosome analysis b) mtDNA (mitochondrial DNA) analysis c) PCR (polymerase chain reaction) analysis d) STRs (short tandem repeats)

Answer 1

b) mtDNA (mitochondrial DNA) analysis

Answer 2

The mitochondrial DNA (mtDNA) is passed down from the mother to the children almost unchanged. The analysis of mtDNA has provided the forensic scientist with essential tools for determining the source of DNA that they have recovered even from small biological samples. Thus, the answer to the question above is letter B.
