Question

how does DNA replicate?

Answer 1

DNA replication begins at specific locations, or origins of replication, in the genome which contains the genetic material of an organism.Unwinding of DNA at the origin and synthesis of new strands, accommodated by an enzyme known as helicase, results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each template strand.
