Question

Extranuclear chromosomes are found in

• A. Peroxysomes and mitrochondria.
• B. Chloroplast and mitrochondria.
• C. Mitrochondria and ribosomes.
• D. Chloroplast and ribosomes.

Answer 1

The correct option is B Chloroplast and mitrochondria.

Extranuclear chromosomes are the chromosomes which are present outside the nucleus in the cytoplasm. The mitochondria have a circular DNA known as mt-DNA and chloroplast has Ct-DNA. This DNA is the site of extranuclear chromosomes. These chromosomes are responsible for the inheritance of extrachromosomal characters.

So, the correct answer is option B.
