Question

Mitochondrial DNA can be taken from bone, hair, or teeth and used in DNA typing. What are the benefits to using mitochondrial DNA over nuclear DNA? mtDNA requires a much smaller sample than nuclear DNA. mtDNA is useful if the nuclear DNA is degraded. mtDNA is inherited from the mother and father’s egg cells, unlike nuclear DNA. mtDNA is present in all maternal relatives of the person being investigated.

Answer 1

A,B,D is the right answer

Answer 2

Answer: mtDNA requires a much smaller sample than nuclear DNA.

mtDNA is useful if the nuclear DNA is degraded.

mtDNA is present in all maternal relatives of the person being investigated.  

Mitochondrial DNA is a type of DNA that is inherited from the mother therefore, it can be found nearly similar in DNA typing of all maternal relatives. It provides valuable locus for forensic DNA typing. The chances and amount of recovery of mitochondrial DNA from the biological samples obtain from the scene of crime is greater than nuclear DNA. It can be obtained from the extremely small amount of biological samples.
