An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene.<span> This is how mitochondrial DNA (mtDNA) typing is used in forensic science.</span>
<span>Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.</span>
I think its arroyo.
i hope this answer is correct and helps you :)
Sorry to take up a answer but the picture is not in the correct format for brainly!!! Upload again so I can help.
MRNA or messenger RNA. As the central dogma of biotech goes, DNA is transcribed to mRNA which is translated to tRNA, after which the amino acids form peptide bonds and form proteins. So when you see transcription, the first thing you think of is DNA to mRNA.
