I believe that there may actually be six total enzymes instead of five, but they should be the helicase, gyrase, primase, DNA polymerase I, DNA polymerase III, and ligase. Below are the descriptions for each enzyme:

Helicase: unwinds the DNA double helix

Gyrase: relieves the buildup of torque during unwinding

Primase: lays down RNA primers

DNA polymerase I: replaces RNA primers with DNA

DNA polymerase III: main DNA synthesis enzyme

Ligase: fills in the gaps
