Structural Genes
These are majority of genes, which produce a specific polypeptide which may act, directly or in combination with other peptides to form enzymes or structural proteins. Such genes are called structural genes. In bacteria these genes usually occur as a cluster on the chromosome, the region being called an operon Such multigenic operons produce single molecule of mRNA initiated by the binding of RNA polymerase to a promoter sequence at one end of the operon
