|
|
|
any cell that has its DNA in a separate nuclear membrane (ex. animal and plant cells)
|
eukaryotes

infectious diseases
|
|
|
any disease that cannot be transmitted between people and is caused by genetics, environment or diet
|
non-infectious diseases
|
|
|
prokaryote cell that can reproduce by binary fission and conjugation
|
bacteria
|
|
|
small hairs used by bacteria for attachment and reproduction
|
pili
|
|
|
long hairs used by bacteria for movement

cell wall
|
|
|
inside shell of a bacteria cell; allows food/waste movement

|
|
small circular chromosome that is swapped in bacterial conjugation
|
plasmid
|
|
|
bacterial reproduction that results in two identical cells
|
binary fission
|
|
|
bacterial reproduction that results in more variation due to swapping of DNA between 2 cells
|
conjugation
|
|
|
spherical shaped bacteria
|
cocci

|
|
rod (rectangular) shaped bacteria

bacilli
|
|
|
spiral shaped bacteria
|
spirilia
|
|
|
nonliving piece of DNA wrapped in a protein coat that requires a host cell to reproduce
|
virus
|
|
|
coating around a viruses DNA
|
protein coat
|
|
|
part of a virus that is used to attach and infect a host cell (also term for any protein found on the outside of a cell membrane)
|
antigen
|
|
|
viral reproduction cycle that results in host cell rupture to release 100's of new viruses
|
lytic cycle
|
|
|
viral reproduction cycle that results in viral DNA merging into host cell's DNA; no symptoms felt
|
lysogenic cycle
|
|
|
stage of lytic cycle in which host cell bursts open
|
lysis stage
|
|
|
stage of lytic cycle in which virus antigen connects with host cell membrane
|
attachment stage
|
|
|
stage of lytic cycle in which virus injects its DNA into host cell and disables host cell
|
entry stage
|
|
|
stages of lytic cycle in which virus takes over host cell to manufacture virus particles
|
replication stage
|
|
|
stage of lysogenic cycle in which viral DNA merges with host cell DNA
|
incorporation stage
|
|
|
stage of lysogenic cycle in which host cell reproduces and copies viral DNA along with its own chromosome; no symptoms felt
|
cell reproduction stage
|
|
|
lysogenic viruses that can switch back to lytic cycle
|
temperate viruses
|
|
|
What can result from the lysogenic cycle viruses depending on where they insert their DNA?
|
cancer
|
