5.Molecular Basis of Inheritance
medium
In his experiments on the chemistry of $DNA$, Chargaff estimated the base composition of human sperms and found that Adenine constituted $31\%$ and Guanine $19\%$. The quantity of Cytosine in the $DNA$ of human somatic cell is likely to be
A
$31\%$
B
$19\%$
C
$38\%$
D
$68\%$
Solution
(b)$19\%$; because '$G$' is always attached with '$C$' $(G \equiv C)$, thus percentage of $C$ will always be equal to $G$.
