Cell Cycle

Question 1 • First Semester Biology

Disruptions in the cell cycle can lead to serious health problems. Which statement best describes cancer cells as a result of disrupted cell cycle regulation?

Answer
A
Cancer cells cannot enter the circulatory system.
B
Cancer cells grow in a controlled and regulated manner.
C
Cancer cells spread to other parts of the body.
D
Cancer cells lose nutrients to healthy cells.

Explanation

When cell-cycle regulation is disrupted, cells can divide uncontrollably and form tumors. Some cancer cells can break away and travel through the blood or lymph to establish tumors elsewhere in the body; this is called metastasis. Therefore, “Cancer cells spread to other parts of the body” is the best description.
