During $DNA$ replication, Okazaki fragments areused to elongate
$A$: Kornberg enzyme is associated with the removal of primers and thyminedimer.
$R$: $DNA$ polymersase I does exonuclease activity in $5^{\prime} \rightarrow 3^{\prime}$ and $3^{\prime} \rightarrow 5^{\prime}$ directions.
In tertiary structure of $DNA$, what is a histone octamer?
A complex consisting of eight positively charged histone proteins (two of each $H2A, H2B, H3 and H4$) that aid in the packaging of $DNA.$
