Web8 de jun. de 2024 · An RNA primer is synthesized by primase and is elongated by the DNA polymerase. On the leading strand, only a single RNA primer is needed, and DNA is synthesized continuously, whereas on the lagging strand, DNA is synthesized in short stretches, each of which must start with its own RNA primer. The DNA fragments are … WebDNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA … WebAs a result, primers synthesized by Pol α on the lagging strand are mutagenic if not removed. This problem is circumvented by the proof-reading property of Pol δ, which interacts with Pol α and collaborates with FEN1 and DNA ligase to remove the primers during the maturation of Okazaki fragments. highlands village winchmore hill
