The DNA present in chloroplast is:
Updated On: Jan 13, 2026
- Linear, double stranded
- Circular, double stranded
- Linear, single stranded
- Circular, single stranded
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Chloroplasts are organelles found in the cells of plants and some algae. They are responsible for photosynthesis, the process by which light energy is converted into chemical energy stored in glucose. Similar to mitochondria, chloroplasts contain their own genetic material, which is distinct from the DNA found in the cell nucleus.
The DNA present in chloroplasts has specific characteristics:
- Circular Structure: Unlike linear DNA, which has ends, circular DNA forms a closed loop with no free ends. This circular structure is similar to bacterial DNA, aligning with the endosymbiotic theory that chloroplasts originated from ancient bacteria.
- Double Stranded: The DNA in chloroplasts has a double-helix structure, consisting of two complementary strands. This is the standard form of DNA structure found in most living organisms, allowing it to store genetic information efficiently.
Given these characteristics, the correct answer to the question regarding the DNA present in chloroplasts is: Circular, double stranded
