Vedclass · Answer

(B) Histones are basic proteins found in eukaryotic chromosomes,which are rich in positively charged amino acids like lysine and arginine.These proteins are essential for the packaging of negatively charged $DNA$ into chromatin.There are five major types of histone proteins: $H_1, H_2A, H_2B, H_3$,and $H_4$.While both the Assertion and the Reason are scientifically correct statements,the Reason describes the types of histones but does not directly explain why they are important for packaging (which involves their basic nature and charge).Therefore,the Reason is not the correct explanation for the Assertion.

Assertion : Histones are basic proteins of major importance in packaging of eukaryotic $DNA$. $DNA$ and histones comprise chromatin forming the bulk of eukaryotic chromosome.
Reason : Histones are of five major types $H_1, H_2A, H_2B, H_3$ and $H_4$.
