Question

cancer cells do not respond to signals that regulate what process?
transcription
metabolism
cell cycle

Explanation:

Cancer cells are characterized by uncontrolled growth and division. They do not respond to signals that regulate the cell - cycle, which is responsible for the orderly progression of cell growth, DNA replication, and cell division. Transcription is the process of making RNA from DNA, and metabolism is the set of life - sustaining chemical reactions in organisms. But the key process that cancer cells evade regulation of is the cell cycle.

Answer:

cell cycle
