$E. coli$ has $4.6 \times 10^6 \text{ bp}$, its rate of multiplication during replication is about $ . . . . . . $ per second. (in $\text{ bp}$)

$DNA$ polymerase is required for:

During $DNA$ replication,which of the following does not act as a substrate?

Depending upon the chemical nature of the template ($DNA$ or $RNA$) and the nature of nucleic acids synthesized from it ($DNA$ or $RNA$),list the types of nucleic acid polymerases.

$E. coli$ has only $4.6 \times 10^{6}$ base pairs and completes the process of replication within $18$ minutes; then the average rate of polymerisation is approximately

$^{15}N$ labeled $E. coli$ is allowed to grow in a $^{14}N$ medium. The two strands of the $DNA$ molecule of the first generation bacteria have:
