The mitochondrial DNA can be used to identify a species based upon
A)NADH dehydrogenase sequences.
B)variation in the mitochondrial ribosomes.
C)648 bp DNA bar code region.
D)leucine codon usage.
E)none of the above

Question

Quizplus · Accepted Answer

The DNA bar code region is a segment of the mitochondrial DNA that is commonly used for species identification because it exhibits high levels of sequence variation between different species. This allows for a relatively easy and accurate method of identifying species using molecular techniques. However, the other options listed (NADH dehydrogenase sequences, mitochondrial ribosomes, and leucine codon usage) are not commonly used for species identification.
