DNA Replication Replication is semi-conservative (one strand is old, one strand new) Each strand serves as a template (or pattern) for the new strand.

REPLICATION OF DNA · DNA strand substrate elongated DNA strand •The nature of DNA replication is a series of 3´- 5 ´phosphodiester bond formation catalyzed by a group of enzymes.
