Which of the following statement is correct about $DNA$ polymerase?
$DNA$ polymerase can synthesize $mRNA$ in the $3 ' to 5 '$ direction.
$DNA$ polymerase can synthesize $DNA$ in the $5 ' to 3 ' $ direction.
$DNA$ polymerase can synthesize $mRNA$ in the $5^{\prime}$ to $3 ' $ direction.
$DNA$ polymerase can synthesize $DNA$ in the $3^{\prime}$ to $5^{\prime}$ direction.
The experimental proof for. semiconservative replication of $DNA$ was first shown in a
Bacteria were grown in a medium containing heavy isotope of nitrogen ($N^{15}$) for many generations and all their $DNA$ contained many heavy nitrogen only. A bacterium of this type was transferred to normal medium and allowed to duplicate. After two divisions of heavy $DNA$ is likely to be that
A $DNA$ molecule in which both strands have radioactive thymidine is allowed to duplicate in an environment containing non-radioactive thymidine. What will be the correct number of $DNA$ molecules that contain some radioactive thymidine after three duplications
$DNA$ repairing is done by
