First, here is a short video that might help:

Enzymes involved in DNA replication are:

  • Helicase (unwinds the DNA double helix)
  • Gyrase (relieves the buildup of torque during unwinding)
  • Primase (lays down RNA primers)
  • DNA polymerase III (main DNA synthesis enzyme)
  • DNA polymerase I (replaces RNA primers with DNA)
  • Ligase (fills in the gaps)
