The process of making a copy of DNA is called DNA and it occurs during phase of interphase. Before replication can begin, the double helix must unwind. After being unwound, the DNA strands are separated by the enzyme . Helicase separates the DNA molecule by breaking the bonds between the nitrogen bases. With the DNA strands separated, DNA polymerase can come in and add complementary (matching) to the separated strands of DNA. When DNA polymerase passes over an adenine (A), it will attach a. DNA polymerase will also match with guanine (G). DNA polymerase will also proofread the new strands of DNA to check for mis-paired nitrogen bases. The process of DNA replication produces two strands of DNA. The new DNA molecules are made of one strand of DNA and one strand of DNA. The new DNA molecules will wind up to return to their double helix shape and prepare for cell division.
