Question:
Which of the following statement about the tails of the histone molecules is NOT true?
Which of the following statement about the tails of the histone molecules is NOT true?
Show Hint
Histone tails: N-terminal, unstructured, modified.
Not required for nucleosome association.
Important for chromatin regulation.
Not required for nucleosome association.
Important for chromatin regulation.
Updated On: Aug 18, 2026
- N-terminal extension
- Lack defined structure
- Site for extensive modifications
- Required for the association of nucleosome
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Histone tails are important for chromatin structure.
They have specific features.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand histone tail properties.
Step 3: Detailed Explanation:
Histone tails:
- Are N-terminal extensions (A is true).
- Lack defined structure (B is true).
- Are sites for extensive modifications (C is true).
Histone tails are NOT required for the association of nucleosomes.
The core histones are required for nucleosome association.
Thus, D is not true.
Step 4: Final Answer:
The statement "Required for the association of nucleosome" is NOT true.
Hence, the correct option is (D).
Histone tails are important for chromatin structure.
They have specific features.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand histone tail properties.
Step 3: Detailed Explanation:
Histone tails:
- Are N-terminal extensions (A is true).
- Lack defined structure (B is true).
- Are sites for extensive modifications (C is true).
Histone tails are NOT required for the association of nucleosomes.
The core histones are required for nucleosome association.
Thus, D is not true.
Step 4: Final Answer:
The statement "Required for the association of nucleosome" is NOT true.
Hence, the correct option is (D).
