How is mitochondrial DNA (mtDNA) typing used in forensic science? An unknown mtDNA sample is matched to a sample of nuclear DNA that was found at a crime scene. An unknown mtDNA sample is matched to a sample of mtDNA that was found at a crime scene. An unknown nuclear DNA sample is matched to a sample of nuclear DNA that was found at a crime scene. An unknown nuclear DNA sample is matched to a sample of mtDNA that was found at a crime scene.

(mtDNA) Used in forensic science

Explanation:

An unknown mtDNA test is coordinated to an example of mtDNA that was found at the wrongdoing scene.  This is the means by which mitochondrial DNA (mtDNA) composing is utilized in forensic science.  Not at all like atomic DNA composing, mtDNA seclusion is very simple since its number is very enormous.  mtDNA duplicates rang from 100 to 10,000 for every cell.  It is likewise more steady and more grounded than the atomic DNA that is the reason even unsolved cases from years back use mtDNA composing as reference for the conceivable end.Hence, the right answer is "An unknown mtDNA  sample is matched to a sample of mtDNA that was found at a crime scene".
