Concepts 。 DNA replication is a very complex process involving a variety of proteins and a number of steps.It is designed to operate rapidly while minimizing errors and correcting those that arise when the DNA sequence is copied. The actual transfer of genetic material between bacteria usually takes place in one of three ways:direct transfer between two bacteria temporarily in physical contact (conjugation),transfer of a naked DNA fragment (transformation),or transport of bacterial DNA by bacteriophages (transduction) Concepts • DNA replication is a very complex process involving a variety of proteins and a number of steps.
