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
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. Positive, Negative
B. Negative, Positive
C. 4.2
D. 16.4
Show Hint
Histones play an essential role in DNA packaging, and their positive charge helps in the binding with negatively charged DNA.

Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
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.
