Title: Why are leading and lagging strand primers removed rather than joined with Okazaki fragments?
Post by: cmperez1988 on Jan 4, 2022
Why are leading and lagging strand primers removed rather than joined with Okazaki fragments?

▸ The primers do not hydrogen bond to the template strand correctly.

▸ They have to be removed for leading and lagging strand synthesis to begin.

▸ Primers are too short to efficiently bind to Okazaki fragments.

▸ They contain nucleotides with 2'OH groups, and are targeted for excision by DNA Polymerase.

▸ They lack the 3' OH that would permit them to be covalently linked to the Okazaki fragments.
