$A$ discrete multiprotein structure on the chromosome which contains enzymes for $DNA$ duplication is called as

During $DNA$ replication, the two strands separate. Each of these acts as a template for the synthesis of a new strand. This mode of replication is called:

New $DNA$ synthesis occurs in the $P$ direction,and the $DNA$ polymerase enzyme reads the template in the $Q$ direction.
$\quad \quad \quad \quad P \quad \quad \quad \quad \quad Q$

During in vitro synthesis of $DNA$,a researcher used $2', 3'$-dideoxy cytidine triphosphate as raw nucleotide in place of $2'$-deoxy cytidine. What would be the consequence?

Given below are two statements.
Statement $I$ - The template strand with free $3'$ end is called leading template and the strand with free $5'$ end is called lagging template.
Statement $II$ - Replication always starts at the $3'$ end of the template strand and proceeds towards the $5'$ end of the template.
In the light of the above statements,select the correct option given below:

What is the full form of $RTase$?
