|
Lytic Cycle
|
T4 phage binds to bacteria and hijacks cellular machinery, uses cell to produce its DNA and proteins, host cell lyses releasing newly assembled virons
|
|
|
Lysogenic Clycle
|
virus injects its DNA and it gets incorporated by the hosts DNA
|
|
|
Plasmid
|
small pieces of circular DNA that are not essential for the functioning of the cell but can be inserted into cell (antibiotic resistance)
|
|
|
Bacteria
|
unicellular, multiply by binary fission
|
|
|
Gram Positive Bacteria
|
Thick peptidoglycan layer (90%)
|
|
|
Gram Negative Bacteria
|
thin peptidoglycan layer (20%), also has periplasmic space and lipopolysaccharide layer, has endotoxin
|
|
|
Flagellum
|
made of protein flagellin, for motility
|
|
|
Endospore
|
Fored under stressful conditions, can be dormant for many years, survive heat, radiation etc. Whe conditons become favorable, activate - germination
|
|
|
Chemoautotrophs
|
build organic macromolecules from CO2 using energy of chemicals
|
|
|
Chemoheterotrophs
|
require organic molecules such as glucose as source of CO2
|
|
|
Photoautotrophs
|
use CO2 only, energy from Sun
|
|
|
Photoheterotrophs
|
Require Sun energy but use organic molecules made by another organism
