Occurs during reproduction between generation of cells
Vertical gene transfer
The transfer of genes between cells of the same generation
Horizontal gene transfer
When Dna in one cell ends up in the DNA of another
Genetic recombination
When two chromosomes break and rejoin
crossing over
Catalyzes the joining of the two strands of DNA in genentic recombination...what protein?
Rec A
The process when bacteria take DNA from the enviroment is called?
Transformation
DNA that is in the enviroment and not in a cell is called?
naked DNA
F+ cell has a plasmid that gives the cell the abilty to grow what?
A pilus
The F+ cell connects it's pilus to an f- cell which is know as what?
Bacterial conjunction
In bacterial conjunction what is it that the f+ cell is giving to the F- cell?
The f factor
An f+ cell plus an f- cell=
an f+ cell because it has the f factor(to grow pilus)
When the combination between f factor and chromosome occur at the same site on each what kind of cell does it produce? Does not have a seperate plamid, it is intertwined in the chromosome
Hfr cell (high frequency recombination)
Hfr + f- =
recombinant f- cell, f factor does not normally go across only a small portion goes across
A virus that infects a bacteria is called
bacteriophage
bacterial information transfered by a virus is called?
transduction by a bacteriophage
PLasmids that CArries genes for sex pili and transfer of the plasmid
conjugative plasmid
Plasmids that encodes enzymes for catabolism of unusual compounds
dissimilation plasmids
Plasmid that encodes antibiotic resistance
R factors
Known as jumping genes, where segments of DNA that can move from one region of DNA to another
