How many hydrogen bonds are formed in a DNA molecule between nitrogen base with 50 nitrogen base pairs in which thymine is 20.

DNA molecule has length of $476 \stackrel{\circ }{\mathrm{A}}$ with $20\%$ guanosine. Choose the correct features of $\mathrm{DNA}$

$\mathrm{I})$ $56 \mathrm{CTP}$
$\mathrm{II})$ $336$ Hydrogen bonds
$\mathrm{III})$ Total $150$ nucleotides
$\mathrm{IV})$ $84 \mathrm{TTP}$

Assertion $\left(\mathrm{A}\right):$ Between $\mathrm{DNA}$ and $\mathrm{RNA}$, $\mathrm{DNA}$ is a better genetic material.

Reason $\left(\mathrm{R}\right):$ $2^{\text{'}}$ $-\mathrm{OH}$ group present in every nucleotide in $\mathrm{RNA}$ is a reactive group and make $\mathrm{RNA}$ labile and easily degradable.

The correct answer is:

Match the following lists:

The correct match is
