The Okazaki fragments in $DNA$ chain:

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

$A$ $DNA$ 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?

Which enzyme catalyzes the process of reverse transcription?

Given below are two statements:
Statement $I:$
$DNA$ polymerases catalyse polymerisation only in one direction,that is $5^{\prime} \rightarrow 3^{\prime}$.
Statement $II:$
During replication of $DNA$,on one strand the replication is continuous while on the other strand it is discontinuous.
In the light of the above statements,choose the correct answer from the options given below:

The growth of Okazaki fragments in a $DNA$ strand is .....
