Question

In the chromatin the charge of a DNA and associated proteins, the number of types of histones and copies are
A. Positive, Negative
B. Negative, Positive
C. 4.2
D. 16.4

• A. B, D
• B. B, C
• C. A, C
• D. A, D

Hint:

Histones play an essential role in DNA packaging, and their positive charge helps in the binding with negatively charged DNA.

Answer 1

The Correct Option is B

In the chromatin, the charge of DNA is negative, and the associated histones have a positive charge. There are 4 types of histones, and each type has two copies (so there are 8 histone proteins associated with the DNA). This matches the description provided in option B, C.
