What happens during a DNA replication?
DNA replication is a bioloigical procces. The first step to a DNA replication is that an enzyme called helicase separates the DNA strands. An enzyme is any of various protiens as pepsin originating from living cells and capable of producing certain chemical changes in organic substances by catalytic action as in digestion. The second step to DNA replication is that DNA polymerase adds complementary nucleotides to the separated strand of DNA. Polymerase is any of several enzyme that catalyze the formation of a long chain molecule by linking smaller molecular units as nucleotides with nucleic acids. The third and last step to DNA replication is that the DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules. Nucleotides are any of a group of a molecules that when linked together form the building blocks of DNA or RNA and that is what happens during a DNA replication.
