5.Molecular Basis of Inheritance
medium
In $DNA$ if $10\%$ guanine is present, how much thymine is present
A
$10\%$
B
$40\%$
C
$80\%$
D
$20\%$
Solution
(b) $C$ is always equal to $G$ and $T$ is always equal to $A$ in $DNA$.
If $G = 10\%$, then $C = 10\%$
$T$ and $A = 80\%$
Hence $T = 40\%$ and $A = 40\%$
