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
If the distance between two consecutive base pairs is $0.34\, nm$ and the total number of base pairs of a $DNA$ double helix in a typical mammalian cell is $6.6 \times 10^{9}$ $bp,$ then the length of the $DNA$ is approximately
If a double stranded $DNA$ has $20$ per cent of cytosine, calculate the per cent of adenine in the $DNA$.
Which amino acids are present in histones
A nucleoside differs from a nucleotide in not having
