WebSteps of DNA Replication. [Click Here for Sample Questions] Step 1: The initial phase in DNA replication is to 'unfasten' the two-fold helix construction of the DNA. Step 2: This is completed by a protein called helicase that breaks the hydrogen bonds holding the correlative bases of DNA together (A with T, C with G). WebAbstract.
