The double helical structure of $DNA$ was proposed by

In the sugar that differentiates $RNA$ from $DNA$,the presence or absence of the $-OH$ group occurs at which carbon atom?

The total number of hydrogen bonds in a $DNA$ double helix strand,where one strand has the following sequence of bases,is $...........$
$5^{\prime}-G-G-C-A-A-A-T-C-G-G-C-T-A-3^{\prime}$

Which moieties of nucleosides are involved in the formation of phosphodiester linkages present in dinucleotides? What does the word 'diester' in the name of linkage indicate? Which acid is involved in the formation of this linkage?

Codon is present in

The number of hydrogen bonds between guanine and cytosine; and between adenine and thymine in $DNA$ is
