Which Characteristic is Correlated with Cancer Cells and Metastasis

Question

Which characteristic is correlated with cancer cells and metastasis?  
A) Altered nuclear and cytoplasmic controls governing cell growth and division
B) Increased use of aerobic respiration
C) Expansion of the cytoskeleton
D) Normal chromosome number
E) Decreased blood supply to the tumor

Accepted Answer

Cancer cells often have mutations in genes that control cell growth and division, leading to uncontrolled proliferation. This can result in tumors that can spread to other parts of the body (metastasis). These altered controls can affect both nuclear and cytoplasmic functions, leading to changes in cell shape, movement, and other characteristics. Increased use of aerobic respiration, expansion of the cytoskeleton, and decreased blood supply may also be associated with cancer, but they are not directly correlated with metastasis. Normal chromosome number is not necessarily a characteristic of cancer cells, as chromosomal abnormalities are common in many types of cancer.
