본문내용

DNA is always synthesized by template-directed, stepwise incorporation of dNMPs into the 3’-OH end of the growing DNA chain, which elongated in the 5’3’ direction

• Each parental strand of a duplex DNA template is copied by base pairing to produce two daughter molecules identical to one another and to their parent: semi- conservative replication
• Replication of DNA begins and ends at specific sites in the template, termed origins and termini, respectively
• DNA synthesis is catalyzed by DNA-dependent DNA polymerases, but many accessory proteins are required for initiation or elongation
