Circular double-stranded DNA C. Chloroplast Ribosomes III. 70S D. Cytoplasmic Ribosomes IV. 80S Choose the correct answer from the options given below:
Options
- AA-II, B-I, C-III, D-IV
- BA-I, B-II, C-III, D-IV
- CA-II, B-I, C-IV, D-III
- DA-I, B-II, C-IV, D-III
Correct answer
A. A-II, B-I, C-III, D-IV
Step-by-step solution
Chloroplasts are semi-autonomous organelles that contain their own genetic material, which is a small, circular, double-stranded DNA molecule (A-II). The nuclear DNA of eukaryotes is linear and double-stranded, associated with histone proteins (B-I). The ribosomes found in the stroma of chloroplasts are smaller (70S) than the cytoplasmic ribosomes (80S) of eukaryotes (C-III, D-IV). Thus, the correct match is A-II, B-I, C-III, D-IV. Answer: A-II, B-I, C-III, D-IV
