Question

In _____________ replication double stranded DNA begins to unwind at the origin of replication, producing single nucleotide strands that then serve as templates on which new DNA can be synthesized.

Answer 1

During DNA replication, the DNA helix unwinds and the two single strands of DNA then each serve as a template for a new stand to be created. DNA replication is semi-conservative: the new DNA molecule consists of half of the parent DNA molecule.

Step-by-step explanation:

DNA replication begins at the origin of replication. The DNA helix unwinds and separates into two single strands, which serve as templates for the synthesis of new DNA strands. DNA helicase and single-strand binding proteins aid in the unwinding and separation of the strands. The RNA primase synthesizes short RNA primers, which provide the starting point for DNA synthesis by DNA polymerase III. The new DNA strands are elongated in both directions from the replication fork, resulting in the formation of two identical DNA molecules.
