$DNA$ replication is .............

If a hybrid $DNA$ $(^{14}N-^{15}N)$ is allowed to undergo replication twice in a medium containing nucleotides with $^{15}N$ base,then what proportion of light,heavy,and hybrid $DNA$ will be obtained respectively?

During the replication of a bacterial chromosome,$DNA$ synthesis starts at the origin of replication and proceeds in:

Describe the experimental proof for the semi-conservative mode of $DNA$ replication.

Describe various enzymes involved in $DNA$ replication.

$A$: Kornberg enzyme is associated with the removal of primers and thymine dimers.
$R$: $DNA$ polymerase $I$ performs exonuclease activity in $5^{\prime} \rightarrow 3^{\prime}$ and $3^{\prime} \rightarrow 5^{\prime}$ directions.
