Structural Genes

Structural genes are genes that contain instructions for the production of proteins or polypeptides. These proteins and polypeptides form the building blocks of organisms, and are responsible for the structure and function of cellular components. They are integral in the development of various processes, such as metabolism and replication, and are important for the survival of an organism. Structural genes are also key in regulating gene expression as they control the rate at which proteins and polypeptides are produced. As such, they are essential in the maintenance of normal physiological functions in a living organism.
