Answer 1

Gene expression is influenced by various factors, including:

- **Chemicals in the body**: These can include hormones, nutrients, and signaling molecules that can activate or repress gene expression.

- **The brain**: The brain can regulate gene expression through various pathways, including hormonal signals and neurotransmitters that can impact gene activity in other tissues.

- **Senescence**: Cellular senescence can influence gene expression by altering the state of the cell, impacting its ability to respond to stimuli.

While protein synthesis is the process that follows gene expression, it is not a factor that determines gene expression itself. Thus, the most relevant factors from your list are "chemicals in the body," "the brain," and "senescence."
