The mitochondrial DNA in humans encode for how many poplypeptides?(a) 15(b) 13(c) 12(d) 11I have been asked this question during an online interview.My doubt is from Mitochondrial Structure and Function topic in chapter Mitochondrial Structure and Function of Cell Biology

Answer»

Correct CHOICE is (b) 13

The best I can explain: The mitochondria possess their own genetic material and the machinery to manufacture their own RNAs and proteins. The mitochondrial DNA encodes a small number of POLYPEPTIDES which are 13 in humans. These are tightly integrated in the inner mitochondrial membrane along with polypeptides encoded by nuclear genes.
