Match List-I with List-II:List-I List-II A. Histones III. Positively charged basic proteins B. Nucleosome IV. DNA wrapped around histone octamer C. Euchromatin I. Loosely packed chromatin D. Heterochromatin II. Densely packed Chromatin
Choose the correct answer from the options given below:
| List-I | List-II |
| A. Histones | III. Positively charged basic proteins |
| B. Nucleosome | IV. DNA wrapped around histone octamer |
| C. Euchromatin | I. Loosely packed chromatin |
| D. Heterochromatin | II. Densely packed Chromatin |
- A-IV, B-III, C-II, D-I
- A-III, B-I, C-IV, D-II
- A-II, B-III, C-IV, D-I
- A-III, B-IV, C-I, D-II
The Correct Option is D
Solution and Explanation
The correct matches are:
A. Histones - III. Positively charged basic proteins: Histones are positively charged proteins that are crucial for DNA packaging in eukaryotes.
B. Nucleosome - IV. DNA wrapped around histone octamer: A nucleosome is the basic structural unit of chromatin, consisting of DNA wrapped around a histone octamer.
C. Euchromatin - I. Loosely packed chromatin: Euchromatin is the less condensed form of chromatin, which is transcriptionally active.
D. Heterochromatin - II. Densely packed chromatin: Heterochromatin is the highly condensed form of chromatin, which is transcriptionally inactive.
Therefore, the correct option is (4): A-III, B-IV, C-I, D-II.
