Question

Which of the following can result in irregularities leading to cancer?

A. The body programming its cells to die
B. The body using cyclins to regulate the timing of the cell cycle
C. The body failing to respond to signals that slow the cell cycle
D. The body utilizing growth factors in development

Answer 1

The correct answer would be option C.

Cancer refers to a disease in which cells tend to grow and divide abnormally.

There are several causes for the occurrence of cancer which include: spontaneous genetic mutations, radiations, carcinogenic chemicals et cetera.

It results in the inability of the body to respond accurately to the signals that slow down the cell cycle.

Consequently, the cells keep dividing and loss the property of contact inhibition due to which it results in the formation of tumors.

Gradually, tumors result in cancer.

Answer 2

Answer;

C. The body failing to respond to signals that slow the cell cycle

-The body failing to respond to signals that slow the cell cycle: can result in irregularities leading to cancer.

Step-by-step explanation;

-Cancer is caused by uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions are not favorable, therefore, too little activity of these inhibitors can promote cancer.

-Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
