Biology Question on Structure of DNA and RNA
Nucleosome core is made of
A
HI, H2A, H2B and H3
B
HI, H2A, H2B, H4
C
HI, H2A, H2B, H3 and H4
D
H2A, H2B, H3 and H4.
Answer
H2A, H2B, H3 and H4.
Explanation
Solution
Nucleosome core is made up of H,A, H2B. H, and H4. It is about 7-10 nm in diameter, consisting of histones around which a DNA strand, about 120 base pair long is wrapped in chromosomes.
