The different types of enzymes include DNA polymerase which catalyses the formation of the bonds between adjacent nucleotides on each strand of the double strands. It also includes DNA ligase which is responsible for joining okazaki fragments, which are formed as a result of the direction moved by the DNA polymerase on the lagging strand. Lastly, is the DNA helicase which runs between the double strands of DNA and breaks the hyrdogen bonds to unzip/ unwind the DNA molecule.
