DNA replication begins with the unwinding of the double helix at the origin of replication. This process is carried out by the enzyme helicase, which breaks the hydrogen bonds between complementary nitrogen bases of the two DNA strands. This separation creates replication forks and allows each strand to act as a template.
(1) Incorrect — Okazaki fragments are formed on the lagging strand, not the leading strand.
(3) Incorrect — Phosphodiester bonds (backbone) remain intact; they are not broken during initiation.
(4) Incorrect — Bonds between base and sugar (glycosidic bonds) are not broken.
