$DNA$ gyrase,the enzyme that participates in the process of $DNA$ replication,is a type of:

For providing evidence in favour of semiconservative way of $DNA$ replication, Taylor, Woods, and Hughes performed experiments on:

Synthesis of leading and lagging strand require

By what other name is $Gyrase$ known?

Bacteria were grown in a medium containing a heavy isotope of nitrogen $(^{15}N)$ for many generations,and all their $DNA$ contained only heavy nitrogen. $A$ bacterium of this type was transferred to a normal medium and allowed to duplicate. After two divisions,the distribution of heavy $DNA$ is likely to be:

What is the approximate rate of polymerization during $DNA$ replication in $E. coli$?
