During the process of DNA replication, the whole molecule gets copied in the [A] phase of the cell cycle. The DNA strands are separated by the enzyme [B] while [C] keeps it from overwinding. The 2 strands are copied differently. The [D] strand is made continuously, while the [E] strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is [F]. This enzyme can only add nucleotides to an existing strand, so short sequences of [G] made by the enzyme [H] are needed for the process of elongation. In the [U] strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while [K] joins the fragments.

Explanation:

During the process of DNA replication, the whole molecule gets copied in the synthesis or S phase of the cell cycle. The DNA strands are separated by the enzyme helicase while topoisomerase keeps it from overwinding. The 2 strands are copied differently. The leading strand is made continuously, while the lagging strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is DNA polymerase. This enzyme can only add nucleotides to an existing strand, so short sequences of nucleotides (primer) made by the enzyme primase are needed for the process of elongation. In the lagging strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while DNA ligase joins the fragments.
