Non-living organism that lives off of a host cell and causes illness
virus structure consists of...
nucleic acid and capsid
protein coat that surrounds genetic material in virus
takes a long time to kill host cell and continues to reproduce with the virus genetic material inside
intense sickness but kills host cell right away
steps for virus infecting the cell
Docks on the cell
injects genetic material into cells
genetic material goes into cell's nucleus
imports genetic material to your genetic code or DNA
type of cell bacteria is
circular, simple DNA
No membrane bound organelles
oldest bacteria, has capacity to live in extreme conditions
where archaebacteria live
oxygen fee places, high acidic waters, high salt content
characteristics of eubacteria
common, heterotrophic, dependent on others for energy (Feed on dead)
able to make own food
feed off the break down of un-organic items
cell wall, shape, how they obtain energy
classification of a bacteria
how do bacteria obtain energy
autotrophically and heterotrophically
one gender-having no sexual organs
having sexual cells
bacteria transfers a piece of its DNA into another bacteria, creating a slightly different genotype and phenotype
two bacteria form a pili between one another and transfer genetic material
each cell gets an exact copy of the parent cell't genetic material aka binary fission
inner cell wall groups
gram positive-stain purple
Gram negative- stains red/pink
more complex walls with less peptidoglycan buried inside
simpler cell wall with exposed peptidoglycan
how antibiotics work
delve into the cell wall
why can't antibiotics kill viruses?
aren't alive, so no cell wall
the first antibiotics
protein infectious particles that are subviral particles because of simplistic structure
reproduce and be infectious but not alive
