Ans. D. It codes for less than 20% of the proteins involved in respiratory chainIn ETC there are around 67 subunits, out it 13 proteins are coded by Mit DNA, which comes around 19%.Mitochondrial DNA has high mutation rate almost 5 to 10 times that of nuclear DNA.It has 16,569 bpMitochondrial DNA has maternal inheritance
