$A$ genome is the

How many $H$-bonds are present between $G$ and $C$ in the structure of $DNA$?

Identify the correct features of $DNA$ from the following statements:
$(i)$ It is made of two polynucleotide chains.
(ii) The backbone is constituted by sugar and phosphate.
(iii) The two chains have anti-parallel polarity.
(iv) The bases in the two strands are linked through $H$-bonds.
$(v)$ Both chains are coiled in a right-handed fashion.

$DNA$ is acidic due to the presence of:

What are the length of one full turn of the $DNA$ helix and the distance between the two strands (polynucleotides)?

If the distance between two consecutive base pairs in a $DNA$ molecule is $0.34 \ nm$ and the total number of base pairs in a typical mammalian cell is $6.6 \times 10^9 \ bp$,what is the approximate length of the $DNA$ (in $m$)?
