Verified step by step guidance

Understand that DNA replication is the biological process by which a cell duplicates its DNA before cell division.

Recall the main phases of DNA replication, which include initiation, elongation, and termination.

Identify that initiation involves the unwinding of the DNA double helix and the formation of the replication fork.

Recognize that elongation is the step where new complementary DNA strands are synthesized by DNA polymerase enzymes.

Note that transcription and translation are processes related to gene expression, not DNA replication, and that splicing, polyadenylation, and recombination are different molecular processes.
