Transcription is the first step in the product of a structural gene. This process releases RNA which will determine the traits for the gene in question.

The difference between a structural gene and a nonstructural gene can be explained that structural gene is a gene encoding the amino acid sequence of a protein. Non-regulatory gene. A structural gene is a gene that codes for any RNA or protein product other than a regulatory element (i.e. regulatory protein)and then it makes proteins in the cell. However, the nonstructural gene is different from structure gene, for example (nonstructural gene)NS1 Influenza Protein is created by the internal protein encoding, linear negative-sense, single stranded RNA, NS gene segment; which found in Influenzavirus A, Influenzavirus B and Influenzavirus C;

Operon. It contains the promoter, operator, and the structural gene.
