4. Which phrase best describes cancer?
a. absence of cyclins
b. multiple gene mutations
c. uncontrolled cell growth
d. presence of genetic defects

Respuesta :

Answer:

C. Uncontrolled cell growth

Explanation:

Uncontrolled cell growth caused by mutations in genes that control the cell cycle. Cancer cells lack the ability to recognize and control cell growth and reproduction. As a result, they replicate again and again.

Answer:

B: Multiple gene mutations

Explanation:

Mutations can be very small changes, affecting only a few nucleotides or they can be very large, leading to major changes in the structure of chromosomes. Both small and large mutations can affect the behavior of cells. Combinations of mutations in important genes can lead to the development of cancer.
