Question:
In the chromosomes, DNA is associated with histone and non-histone proteins. This was reported in 1974 by -----------------.
In the chromosomes, DNA is associated with histone and non-histone proteins. This was reported in 1974 by -----------------.
Show Hint
Recall who described the nucleosome as the repeating unit of chromatin in 1974.
Updated On: Nov 12, 2026
- F.H.C. Crick
- F. Miescher
- F. Griffith
- R. Kornberg
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
In chromosomes, DNA wraps around a core of histone proteins and non-histone proteins are also attached.
Step 2: Who reported it
Roger Kornberg in 1974 described chromatin as a chain of repeating units called nucleosomes.
Step 3: Why the other options fail
Crick is known for the double-helix model (1953), Miescher for discovering nuclein (1869) and Griffith for the transformation experiment (1928).
Final Answer:
R. Kornberg reported this in 1974. \[ \boxed{\text{(D) }\text{R. Kornberg}} \]
