Step-by-step solution

RNA polymerase catalyzes transcription and inherently facilitates the opening of the DNA helix during this process. Helicase is responsible for unwinding the DNA double helix specifically during DNA replication by breaking the hydrogen bonds between the two strands. DNA ligase joins the discontinuously synthesized DNA fragments (Okazaki fragments) during replication. DNA polymerase (DNA-dependent DNA polymerase) catalyzes the polymerization of deoxynucleotides to synthesize the new DNA strand. Therefore, the correc
