Does the mitochondrial dna sequence amplified by pcr in the dna isolation lab code for functional proteins? select one:

a. no, mitochondrial dna sequences never code for functional proteins.
b. no, the amplified sequence is located in the control region, and therefore does not control the coding of functional proteins.
c. no, only rna sequences and nuclear dna sequences code for functional proteins.
d. yes, all mitochondrial dna sequences code for functional proteins
