.... acting of 2 sets of enzymes - DNA helicase enzymes and DNA polymerase enzymes. The DNA helicase enzymes separate the 2 nucleotide strands. The site where the helicase is working and where replication is taking place is known as the DNA fork. The polymerase enzyme helps the nitrogenous base in a given nucleotide to pick up and attach to a complementary base at the 3' end of the DNA template. The 5'-3' strand of template is duplicated in short segments called Okazaki fragments. Ligase is the e ....
