Which of the following regarding DNA replication, is/are correct?
Which of the following regarding DNA replication, is/are correct?
On the template with polarity 3’
5’, replication is continuous
On the template with polarity 5’
3’, replication is discontinuous
The correct option is D All the above
During DNA replication, both the strands of the parental DNA double helix serve as templates. A template strand is simply the strand from which a new complementary strand is synthesised. Complementary to the 3′→ 5’ template, the leading strand is synthesised along the 5′→ 3’ direction. The lagging strand is synthesised discontinuously, and complementary to the 5’→ 3’ template. Ultimately, one round of DNA replication results in the splitting of a single parental DNA molecule to form two daughter DNA double helices, exactly identical to the parental DNA.
