The three different prokaryotic replication systems that have been most extensively studied use the same basic components for moving a DNA replication fork, even though the individual proteins are different and lack extensive amino acid…
How do polymerases differ in their function on leading and lagging strands?Leading strand DNA polymerase synthesizes continuously, while lagging strand DNA polymerase synthesizes in discrete Okazaki fragments, requiring primase for initiation.What role does the primosome play in prokaryotic DNA replication?The primosome, consisting of RNA primase and helicase, synthesizes RNA primers for lagging strand DNA synthesis at approximately 400 nucleotides per second.How does the structure of a replication fork influence Okazaki fragment synthesis?The replication fork's folding allows the lagging strand DNA polymerase to recycle, ensuring efficient formation of approximately 1200-nucleotide Okazaki fragments.
