Q2 / 180 · AIIMS 2004 · Botany

DNA is present in

  • A
    chromosomes and dictyosomes
  • B
    chloroplasts and lysosomes
  • Correct answer
    C
    mitochondria and chloroplasts
  • D
    mitochondria and endoplasmic reticulum.

Solution

DNA is present both in mitochondria and chloroplast. The DNA molecules are circular, relatively small, double stranded (except for the DNA of some algae and protozoans). The mitochondrial DNA varies in size starting from $5 \mu \mathrm{m}$ to $30 \mu \mathrm{m}$. Average length of chloroplast DNA is $45 \mu \mathrm{m}$.

Hence, the correct answer is option: 'C'.
