Investigator Murray is examining evidence from an old crime scene. She has a blood sample, but she believes that the sample may be too degraded to get DNA from. Investigator Murray decides to try to retrieve mtDNA from the sample and compare it to a sample from her suspect. What information could this sample give her? A The blood at the crime scene belonged to her suspect.
B The suspect has blond hair and blue eyes.
C There is a maternal relation between the two people.
D The person from the crime scene has been near the suspect.

The answer is C.

Explanation:

They explained that "Investigator Murray decides to try to retrieve mtDNA from the sample and compare it to a sample from her suspect. What information could this sample give her?"

mtDNA: Mitochondrial DNA (mtDNA) can also be useful to investigators and is found in the energy-producing organelles called mitochondria. This type of DNA can sometimes be recovered from evidence that is too degraded or old to yield regular DNA. Although mtDNA can't be linked to one individual, it can show that subjects are maternally related, since it is passed down through the maternal side of the family.

I took the test and the definition of mtDNA (also known as Mitochondrial DNA) came from my notes. Have a good one and I hope it helps!! :)

it enhances antibody production by t cells of the adaptive immune system.
