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 $45\mu \mathrm{m}$.
