WebSo the DNA primase is going along the lagging, is going along this side, I can say the top strand, and it's adding, it's adding the RNA primer, which won't be just one nucleotide, it tends to be several of them, and then once you have that RNA primer, then the polymerase can add in the 5' to 3' direction, it can add on the 3' end. Web22 sep. 2024 · In eukaryotic cells, polymerases alpha, delta, and epsilon are the primary polymerases involved in DNA replication. Because replication proceeds in the 5′ to 3′ direction on the leading strand, the newly formed strand is continuous. The lagging strand begins replication by binding with multiple primers. Each primer is only several bases apart.
