The DNA present in chloroplast is
Answer: (A) Circular, double, stranded. Answer: (A) Circular, double, stranded Solution: NCERT states that the stroma of the chloroplast contains small, double-stranded circular DNA molecules along with ribosomes.
- A.Circular, double, stranded✓
- B.Linear, single stranded
- C.Circular, single stranded
- D.Linear, double stranded
Correct Answer
(A) Circular, double, stranded
Solution & Explanation
Answer: (A) Circular, double, stranded Solution: NCERT states that the stroma of the chloroplast contains small, double-stranded circular DNA molecules along with ribosomes. Hence the DNA present in the chloroplast is circular and double-stranded. NCERT Reference: Ch 8, p.98, lines 22-24: "It also contains small, double-stranded circular DNA molecules and ribosomes."
