Cancer cells typically exhibit
A.loss of density-dependent inhibition and anchorage dependence
B.strict checkpoint control
C.slower-than-normal division
D.perfect DNA repair
Explanation
Core Concept
Many cancer cells lose normal controls that limit proliferation when cells become crowded or detached from an appropriate extracellular matrix. Those changes can support abnormal growth and survival. Metastasis, however, requires additional capabilities such as invasion, migration, survival in circulation, and colonization of new tissue, so it should not be reduced to a single checkpoint defect.
Correct Answer
Aloss of density-dependent inhibition and anchorage dependence
