Vedclass · Answer

(A) nucleosome is the basic structural unit of eukaryotic chromatin,which consists of a segment of $DNA$ wrapped around a core of histone proteins.In the provided figure:$A$ represents the $DNA$ molecule that wraps around the histone core.$B$ represents the $H_1$ histone protein,which binds to the $DNA$ where it enters and leaves the nucleosome.$C$ represents the histone octamer,which is the core complex consisting of two molecules each of four histone proteins ($H2A, H2B, H3,$ and $H4$).Therefore,the correct identification is $A - DNA, B - H_1$ histone,and $C -$ Histone octamer.

The given figure shows the structure of a nucleosome with its parts labelled as $A, B$ and $C$. Identify $A, B$ and $C$.
