What are the 3 steps of DNA replication?

Back

1) Helicase unwinds & unzips the DNA helix 2) DNA polymerase adds on free floating nucleotides 3) DNA polymerase proof reads the molecule

Which enzyme is responsible for breaking the weak hydrogen bonds of the complementary base pairs, also known as "unzipping" the DNA?

Back

Helicase
