7.1 Flashcards
G1
first stage of cycle takes the cell and checks it for damages and then gets bigger
G0
where the damaged cells get out of cycle and dont replicate
liver cells also go here
S
where chromosomes are coped
G2
where cell is check one last time before being divided
M1
where cell splits into two sister cells
growth factors
makes the system go
cycilins
drive cell progression with kinasses
cdks
cycilin dependent kinasses is helping make the cycle work and not have mutatins
p53
break pedals
D1
gas Pedal
proto oncogenes
good and help keep things running only one allele and dominant
oncogenes
bad and needs two alleles recessive
tumor suppressors
slows down and allows the cell to not mutate so no cancer is formed
The oncogenes relates to cancer
it causes the process to spread up and causes the mutated cell to make copies of itself and then it spreads making tumors and cancer
mutations in tumor suppressors
can lead to process speeding up and cause cancer
P or T
T both alleles of a gene need to be muted in order for cancer to occur
