Please help! :~) Compare and contrast these mechanisms. Match the items to their respective spots. A: The process is controlled by genes of extrachromosomal elements B: DNA is released after the "donor" cell lyses. C: The process is characterized by infection of the donor cell by a bacteriophage D: DNA enters the "recipient" cell via DNA transporters E: Transforming elements absorb across the cell membrane F: The process rrquires genetic information for transfer which is found in the F plasmid...

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...
