Replication

Replication in biology simply refers to the act or ability to make a copy. (Mostly commonly meaning molecular replication).

• Self-replication refers to the act of a molecule (or any other pattern) making a copy of itself.
• DNA replication the act of copying the genetic material of a cell (DNA) to a daughter cell is almost, but not quite, a form of self-replication because it requires the cellular apparatus to perform that replication.
• Semiconservative replication is the particular mechanism of DNA replication, of several mechanisms that were originally hypothesised, that was found to be actually used in cells.
