Corresponding Item
Ligase
arrow_right_alt
Enzyme that unzips the the double-stranded DNA by breaking the hydrogen bonds holding the bases together
DNA Polymerase
arrow_right_alt
Enzyme that builds a new DNA molecule by adding complementary strands of DNA to the original, unzipped DNA molecule
Helicase
arrow_right_alt
Enzyme that synthesizes a primer so DNA polymerase knows where to begin working
Primase
arrow_right_alt
