Regulatory Sequences
Definition
Regulatory sequences are sections of DNA that control the activity of genes. They determine when, where, and how much a gene is expressed.
Analogy
Think of regulatory sequences like a music conductor. Just as a conductor controls when each instrument plays in an orchestra, regulatory sequences control when each gene 'plays' or gets expressed in our cells.
