3 main methods of GS

Question 1

HGT

Answer 1

movement of GM between organisms to acquire new traits

Question 2

types 3

Answer 2

Transformation, conjugation and transduction

Question 3

Transformation

Answer 3

bacteria taken up by DNA fragments incorporated into genome

DNA binds to surface and enters genome

Used by dna to acq AB resistance e.g neisseria gohnnorhea penicillin

Question 4

Conjugation

Answer 4

Transfer GM via cell-cell contact

Surfaces touch with pilli, partial CL, transfer GM

Spreads AB resistance, e.g E.coli

Question 5

Transduction

Answer 5

Bacteriophage assembles new DNA, accidental transfer e.g cornebacterium spreading neurotoxin

spreads GM to increase survivability
