Gene expression is determined by several factors, including "chemicals in the body." Various chemical signals, such as hormones, neurotransmitters, and other molecules, can influence the transcription and translation processes involved in gene expression. Other factors, such as environmental influences and cellular conditions, can also play a significant role in regulating gene expression.
