Pol α, helps to initiate replication because it forms a complex with primase. In eukaryotes, leading strand synthesis is thought to be conducted by Pol ε; however, this view has recently been challenged, suggesting a role for Pol δ.

Web9. In simple terms: Function of the RNA primer: DNA polymerases need a double-stranded DNA region to which they can attach in order to begin copying the rest of the DNA strand. In order to provide this double-stranded attachment site, RNA primers are added by primase, an RNA polymerase which does not require such an attachment site itself. WebMay 24, 2024 · Leading Strand vs Lagging Strand. During DNA synthesis two new strands of DNA are made. This ultimately creates two semiconservative daughter molecules of DNA, each having one old …
