Question

Assertion : Synthesis of daughter or new strand occurs continuously along the parent $3' \rightarrow 5'$ strand.

Reason : $DNA$ polymerase can polymerise nucleotides in $3' \rightarrow 5'$ direction on $5' \rightarrow 3'$ strand.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

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