|
Homologous Recombination |
Process by which a cell replaces a stretch of DNA with a segment that has a similar nucleotide sequence |
|
|
Horizontal gene transfer |
DNA transfer from one bacterium to another by conjugation, DNA-mediated transformation or transduction |
|
|
Mutation |
A change in the nucleotide sequence of a cell's DNA that is then passed on to daughter cells |
|
