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

Answer is B.

Explanation:

The mitochondrial DNA is found in most eukaryotes mitochondrial, and it is an extranuclear double stranded DNA. It is known to be maternally inherited.

It produces adenosine triphosphate, ATP, which is useful to the cells, through the conversion of chemical energy in the food.

It was discovered that, there are about 2 to 10 copies of the mitochondrial DNA genome in each of the mitochondrion.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
