Question

Many molecular mechanisms mediate cellular adaptation. Some are factors produced by other cells and some by the cells themselves. These mechanisms depend largely on signals transmitted by chemical messengers that exert their effects by altering the function of a gene. Many adaptive cellular responses alter the expression of "differentiation" genes. What can cells do because of this?

Answer 1

Cells can alter the expression of differentiation genes through molecular mechanisms that mediate cellular adaptation. This allows cells to respond to environmental stimuli and coordinate the activity of the whole organism.

Step-by-step explanation:

Cells can alter the expression of differentiation genes due to molecular mechanisms that mediate cellular adaptation. Signals transmitted by chemical messengers can change the function of a gene, leading to adaptive cellular responses. By controlling gene expression, cells can regulate the levels of enzymes and proteins, allowing them to respond to environmental stimuli and coordinate the activity of the whole organism. These mechanisms are crucial for cell specialization and different physiological processes such as cell growth, energy storage, and programmed cell death.
