describe how the leading strand is synthesized
The leading strand synthesis occurs in the 5' to 3' direction with the enzyme DNA polymerase adding new nucleotide bases while the enzyme helicase unwinds the initial double stranded molecule.For continuous replication of the 'lagging strand' DNA polymerase must work in the 3' to 5' direction which is not possible.his poses no problems for the leading strand, which can continuously synthesize DNA in a processive manner, but creates a problem for the lagging strand, which cannot be synthesized in the 3' â 5' direction. Thus, the lagging strand is synthesized in short segments known as Okazaki fragments.
