DNA replication involves helicase unwinding the DNA, followed by free nucleotides pairing with exposed bases, and DNA polymerase forming phosphodiester bonds to create new strands.
DNA replication steps: DNA helicase unwinds DNA by breaking hydrogen bonds. Free nucleotides attach to exposed bases via complementary base pairing. DNA polymerase catalyzes condensation reactions, forming phosphodiester bonds between nucleotides.
