Question

Discontinuous synthesis of $DNA$ occurs in one strand, because

$DNA$ molecule being synthesised is very long

$DNA$ dependent $DNA$ polymearse catalyses polymerisation only in one direction $(5' \rightarrow 3')$

it is a more efficient process

$DNA$ ligase has to have a role

Answer

$DNA$ dependent $DNA$ polymearse catalyses polymerisation only in one direction $(5' \rightarrow 3')$

Explanation

Solution

The $DNA$ -dependent $DNA$ polymerases catalyse polymerisation only in the one direction, that is $5' \rightarrow 3'$ . This creates some additional complications at the replicating fork. Consequently, on one strand (the template with polarity $3'\rightarrow 5'$ ), the replication is continuous, while on the other (the template with polarity $5' \rightarrow 3'$ ), it is discontinuous. The discontinuously synthesised fragments are later joined by the enzyme $DNA$ ligase.
