Which of the following is typical of cancer cells?
A. The parent cell of the tumor contains a single mutation in a single checkpoint gene.
B. Malignant cells migrate.
C. Cancer cells lose the ability to divide.
D. Products of oncogenes inhibit mitosis
E. Benign tumors invade normal tissue.
With regard to cancer cells, which of the following are true?
A.
Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation.
Cells usually accumulate many mutations over time, and this results in cancerous growth.
B.
Almost all cancers are caused by oncogenic viruses.
no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body.
DE.
Cancer cells are unable to control their division.
The normal function of the Rb protein is toa. act as a brake on cell division.b. produce retinoblastoma.c. facilitate retinal pigmentation.d. initiate DNA replication.
