Answer to Question 1

Various nutrients can switch gene expression on or off. The promoter region of a gene acts as the master switch. A large variety of proteins known as transcription factors can bind to areas on the promoter and either enhance or inhibit gene expression. A combination of dietary factors and hormones influences the types of transcription factors that reach the nucleus and their tendency to bind to DNA.
