Mitochondria and chloroplast are (A) semiautonomous organelles (B) formed by division of preexisting organelles and they contain DNA but lack protein synthesising machinery. Which one of the following options is correct? (a) (A) is true but (B) is false. (b) Both (A) and (B) are false. (c) Both (A) and (B) are correct. (d) (B) is true but (A) is false
Option A is correct. Both mitochondria and chloroplast are semi autonomous organelles. They have their own DNA which produces its own, mRNA, tRNA and rRNA. These organelles also possess their own ribosomes and hence are able to synthesise some of their proteins
