True
False
Question 2 2/2pts
Cellular senescence is a process that is exaggerated in malignant cells
and promotes their division and metastasis.
True
False
, Question 3 2/2pts

senescence in the cells observed? Choose all that apply:
Large flattened morphology
Reduced incorporation of 5-bromodeoxyuridine (in DNA replication)
Increased p53 expression
Decreased expression of p15INK4B
