Nucleosome is:
A
Positively charged DNA wrapped around negatively charged histone octamer
B
Negatively charged DNA wrapped around positively charged histone octamer
C
Positively charged DNA wrapped around positively charged histone octamer
D
Negatively charged DNA wrapped around negatively charged histone octamer
Answer
Negatively charged DNA wrapped around positively charged histone octamer
Explanation
Solution
Nucleosomes are the fundamental units of chromatin, where negatively charged DNA is wrapped around a positively charged histone protein octamer. This structure helps in compacting DNA within the nucleus.
