cancer and cell death
what is apoptosis
programmed cell death
true or false: cancer makes cells divide uncontrollably
t
what is benign
a tumor that is not cancerous
what are the stages of mitosis
PMAT
what is a gamate
a reproductive cell
what is necrosis
death of tissue that can spread. not good type of death
what stage is known as the resting stage
interphase
true or false: cancer cells go through uncontrolled mitosis
true
what happens in prophase
chromosomes condense
what is made at the end of meiosis
four genetically different cells
metastasis
elephants have extra copies of this gene
p53
what is a tumor called that is cancerous
malignant
what does mitosis make at the end
2 identical daughter cells with 46 chromosomes
how many rounds of divison does meiosis have
2
three possible treatments for cancer are
chemo, radiation, surgery
what happens in s phase
dna dynthesis
a doctor takes a biopsy of a patient to check for cancer. What would they notice about the cells if the patient had skin cancer
more cells would be in mitosis
what phase of mitosis takes the longest
prophase because the chromosomes have to condense and spindle fibers are forming
what process happens in meiosis that causes genetic variation?
bonus: what stage does it occur in
crossing over
prophase 1
why does necrotic tissue need to be removed?
it will spread
what cell type goes through mitosis? how many chromosomes do these cells have
somatic cells-46 chromosomes
cancer causing genes are called
oncogenes
mitosis purpose is?
to replace old or damaged cells
what is the purpose of meiosis
to make gamate cells
