In the chromosomes, DNA is associated with histone and non-histone proteins. This was reported in 1974 by -----------------.
- AF.H.C. Crick
- BF. Miescher
- CF. Griffith
- Correct answerDR. Kornberg
Solution
In 1974, R. Kornberg reported that in chromosomes, DNA is associated with histone and non-histone proteins to form the basic structural unit of chromatin, which is known as the nucleosome.
F.H.C. Crick co-discovered the double helix structure of DNA in 1953.
F. Miescher discovered nucleic acids (nuclein) in 1869.
F. Griffith discovered the transforming principle in 1928.
