The chart above summarizes the distinguishing criteria for the three main processes of recombination that occur in bacterial cells. Which of the following would fill in the blanks 1. and 2. Correctly? The parasexual process in which competent bacteria can acquire new genetic material through the uptake of extracellular DNA molecules is called: An small extra-chromosomal circular genetic element that replicates independently of the bacterial chromosome is called: Both the F factor and the Hfr chromosome containing the integrated F factor replicate during the transfer of DNA from donor cell to recipient cell via a mechanism called: Because viral particles absolutely require host cell machinery to propagate they are said to be:

Once a lysogenic virus has integrated its viral DNA into the host cell chromosome and its lytic genes are turned off, it is said to be: Bacterial mutants that are incapable of producing an enzyme/s required for the synthesis of an essential metabolite and therefore require the addition of a nutrient supplement into growth medium are called: A relatively large extra-chromosomal genetic element that can be either integrated into the bacterial chromosome or remain separate and replicate independently is called: Cell surface appendages coded by genes found on the F factor episome, which function to attach to a recipient F- bacterial cell pulling it within close contact to the F+ donor cell are called: During conjugation between an F+ cell/Hfr cell and an F- cell (F+ x F- or Hfr x F-) the cellular bridge, coded by genes within the F factor, that is formed between donor and recipients cells and through which the bacterial DNA passes is called the: The parasexual process in which bacterial genetic material can be transferred from one cell to another via subsequent bacteriophage infection is called:
