On which strand replication is continous
Web29 de nov. de 2024 · Continuous DNA synthesis, as in the leading strand, would need to be in the 3′ to 5′ direction, which is impossible as DNA polymerase cannot add bases to the 5′ end. Instead, as the helix unwinds, RNA primers are added to the newly exposed bases on the lagging strand and DNA synthesis occurs in fragments, but still in the 5′ to 3′ … WebQuestion: Above is shown a schematic of a DNA strand annealed to an RNA primer produced by Primase during replication. a.
