How are enzymes to the process of dna replication ? what are the names and functions of the specific enzymes used ?

DNA Helicase - unwinds the double helix by disrupting H bonds that bind the nitrogenous bases

Single-stranded binding proteins - prevent the separated DNA strands from re-attaching

RNA Primer - made up of multiple nitrogenous bases which are attached to the template strand and initiate the building of a new complementary strand i.e replication 

Primase - builds RNA primers

DNA Polymerase I - removes RNA primers and replaces them with appropriate DNA nucleotides

DNA Polymerase III - creates complementary strands of DNA, attach to an RNA primer, and add nucleotides to the 3' end 

DNA Ligase - joins Okazaki fragments together by phosphodiester bonds 

DNA Gyrase - relieves tension produced when DNA double helix is unwound by helicase
