On which strand o f DNA, replication is continuous?

Question

On which strand o f DNA, replication is continuous? (A) 5' → 3' polarity strand (B) 3' → 5' polarity strand (C) 3'→ 2' polarity strand (D) 3' → 4' polarity strand

Tardigrade Admin · Accepted Answer

The replication is continuous on 3' 5' polarity strand because DNA polymerase can catalyse polymerisation in 5' → 3' direction only and we know that DNA strands are complementary to each other. Thus, continuous synthesis occurs in 3' → 5' direction.

Q. On which strand o f DNA, replication is continuous?

$5^{'} \to 3^{'}$ polarity strand

$3^{'} \to 5^{'}$ polarity strand

$3^{'} \to 2^{'}$ polarity strand

$3^{'} \to 4^{'}$ polarity strand

The replication is continuous on $3^{'} 5^{'}$ polarity strand because DNA polymerase can catalyse polymerisation in $5^{'} \to 3^{'}$ direction only and we know that DNA strands are complementary to each other. Thus, continuous synthesis occurs in $3^{'} \to 5^{'}$ direction.

Q. On which strand o f DNA, replication is continuous?

5′→3′ polarity strand

3′→5′ polarity strand

3′→2′ polarity strand

3′→4′polarity strand

The replication is continuous on 3′5′ polarity strand because DNA polymerase can catalyse polymerisation in 5′→3′ direction only and we know that DNA strands are complementary to each other. Thus, continuous synthesis occurs in 3′→5′ direction.

$5^{'} \to 3^{'}$ polarity strand

$3^{'} \to 5^{'}$ polarity strand

$3^{'} \to 2^{'}$ polarity strand

$3^{'} \to 4^{'}$ polarity strand

The replication is continuous on $3^{'} 5^{'}$ polarity strand because DNA polymerase can catalyse polymerisation in $5^{'} \to 3^{'}$ direction only and we know that DNA strands are complementary to each other. Thus, continuous synthesis occurs in $3^{'} \to 5^{'}$ direction.
