If a double stranded DNA has $20\; \%$ of cytosine, what will be the percentage of adenine in it?

$20\; \%$

$40\; \%$

$30\; \%$

$60\; \%$

Solution

The purines and pyrimidines are always in equal amounts as per chargaff's rule. So, if cytosine is $20\; \%$, the thymine will be $30 \%$ and thymine is equal to adenine. Then the percentage of adenine will be $30\; \%$.

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 $H_4$ .
