Logistic growth Population growth that is controlled by limited resources
Conjugation A temporary union of two organisms for the purpose of DNA transfer
Plasmid A small, circular section of extra DNA that confers one or more traits to a bacterium and can be reproduced seperately from the main bacterial genetic code
Transformation The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell
