Applications of DNA Technology

Question 9 • Biology_A_IC

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?

Answer
Y
Y-chromosome analysis
m
mtDNA (mitochondrial DNA) analysis
P
PCR (polymerase chain reaction) analysis
S
STRs (short tandem repeats)

Explanation

Mitochondrial DNA is inherited from the mother, so a missing person’s mtDNA can be compared with mtDNA from maternal relatives. This makes mtDNA analysis the appropriate technology. Y-chromosome analysis follows the paternal line, while PCR and STRs are not specifically based on maternal inheritance.
