Why Is Primase Needed
Primase is a type of RNA polymerase enzyme that synthesises a short RNA primer for DNA replication. It initiates the... View Article

Does Dna Replicate In Both Mitosis And Meiosis
Yes, DNA replicates in both mitosis and meiosis. In meiosis, the cell undergoes two divisions, i.e. meiosis I and II.... View Article
Is There DNA Replication In Mitosis
DNA replication occurs before mitosis as well as meiosis. DNA replication occurs during the S phase of the cell cycle.... View Article
Does Dna Replication Occur Before Mitosis
Yes, DNA replication occurs at the interphase, during S-stage of the cell cycle. The cell cycle consists of 4 stages,... View Article
What Happens If Dna Replication Does Not Occur

Why Are Okazaki Fragments Necessary
Okazaki fragments are necessary for the replication of both strands simultaneously. As DNA polymerase can only add nucleotides in 5’→3’... View Article
Why Do Okazaki Fragments Form
DNA polymerase can synthesise new strands in only 5’→3’ direction so the template strand of the DNA having 5’→3’ polarity... View Article
