A) The ability of cancer cells to cross the basal lamina is a relatively unimportant factor in
determining whether they will metastasize to form secondary tumors.
B) Cancer cells gradually accumulate a variety of mutations that cause them to progressively
become less responsive to the external signals that normally control cell growth.
C) Over half of human tumor cells exhibit mutations in the p53 gene.
D) The proliferation of cancer cells is sensitive to compounds that block microtubule
depolymerization.
E) Cancer cells generally retain normal cell cycle checkpoint functions.

True or False. For either response, please justify your answer.

D) The proliferation of cancer cells is sensitive to compounds that block microtubule

E) Cancer cells generally retain normal cell cycle checkpoint functions.

cancer cells shows anormal cell division and show different chromsomes number due abnormal division , in relation microtubule depolymerization.

50. True One possible function of a tumor suppressor gene is to control a cell cycle
checkpoint.

failure of tumor suppressor gene and mutation of tumor suppressor gene    in cell cycle leads to cancer cell.
