Which of the following correctly describes the type of DNA found in both mitochondria and chloroplasts?

Options

  1. ALinear, double-stranded DNA
  2. BCircular, single-stranded DNA
  3. CCircular, double-stranded DNA
  4. DLinear, single-stranded DNA

Correct answer

C. Circular, double-stranded DNA

Step-by-step solution

Mitochondria and chloroplasts are semi-autonomous organelles that possess their own genetic material. According to NCERT, both of these organelles contain circular, double-stranded DNA molecules, unlike the linear double-stranded DNA found in the nucleus of eukaryotic cells. Therefore, the genetic material common to both is circular and double-stranded. Answer: Circular, double-stranded DNA
