DNA -polymerase can polymerise nucleotides only in 5' arrow 3' direction on 3' arrow 5' strand because it adds them at the 3' end.

Q. Assertion : Synthesis of daughter or new strand occurs continuously along the parent $3^{'} \to 5^{'}$ strand.

Reason : $D N A$ polymerase can polymerise nucleotides in $3^{'} \to 5^{'}$ direction on $5^{'} \to 3^{'}$ strand.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

$D N A$ -polymerase can polymerise nucleotides only in $5^{'} \to 3^{'}$ direction on $3^{'} \to 5^{'}$ strand because it adds them at the $3^{'}$ end.

Q. Assertion : Synthesis of daughter or new strand occurs continuously along the parent 3′→5′ strand. Reason : DNA polymerase can polymerise nucleotides in 3′→5′ direction on 5′→3′ strand.
