The problem of replication the lagging strand --- that is, adding bases in the 3'--->5' direction?

The problem of replication the lagging strand --- that is, adding bases in the 3'--->5' direction on a discontinuoes process --- is solved by DNA through the use of

a) base- pairing b) replication forks c) the unwinding enzyme, helicase d) Okazaki fragments e) topoisomerases

help :/

thank you

    DNA ligase is what binds the discontinuous fragments also called Okazaki fragments my friend. base-pairing is the hydrogen bonding that happens between the nucleotides of two strands; C triple bond G and A double bond T. Replication fork contains DNA Polymerase and other factors which bind to 3'-OH and starts the addition of nucleotides on the new strand. helicase is like a stone it holds the unwind two strands apart. topoisomerase is like helicase but it unwinds complex winds b4 helicase. wish I've helped. ::)

    D) okazaki fragments

    what happens is the DNA polymerase copies little strands in the five to three direction (against the flow of the strand) and so they make little fragments that need to be connected together later by ligase, another enzyme
