Recombination: Intermicrobial DNA Exchange Flashcards
factors involved in conjugation
donor cell with pilus
fertility plasmid in donor
both donor and recipient alive
bridge forms between cells to transfer DNA
Transformation factors invovled
free donor (DNA) fragment or plasmid
live, competent, recipient cell, donor usually dead
Transduction factors involved
Donor is lysed bacteria cell
defective bacteriophage is carrier of donor DNA
Live recipient cell of same species as donor
drug resistance; resistance to metal toxin production; enzymes; adherence molecules; degradation of toxic substance; uptake of iron are all examples of
conjugation
polysaccharide capsule; metabolic enzymes; drug resistance; unlimited cloning techniques are all examples of
transformation
exotoxins; enzymes for sugar fermentation; drug resistance are all examples of
transduction
