nucleosome

Vedclass · Answer

(A) The correct answer is $(A)$. The diagram shows a nucleosome. $A$ nucleosome is the basic structural unit of $DNA$ packaging in eukaryotes. It consists of a segment of negatively charged $DNA$ wrapped around a positively charged histone octamer (a complex of eight histone proteins). The $H_1$ histone protein helps in stabilizing the structure by binding to the $DNA$ where it enters and leaves the nucleosome.
