Question

Quizplus · Accepted Answer

Checkpoint proteins ensure that cells do not progress through the cell cycle if there are any errors, genetic abnormalities, or other issues that could lead to uncontrolled growth or cancer. Mutagens can cause genetic abnormalities, but they do not prevent cells from progressing through the cell cycle. UvrA-D proteins are involved in repairing DNA damage caused by UV radiation, but they do not directly prevent uncontrolled cell growth. Growth factors and Ras proteins can promote cell growth and division, but they do not prevent cells from progressing through the cell cycle if there are genetic abnormalities.
