What Are The Four Parts Of An Operon? An operon consists of an operator, promoter, regulator, and structural genes. What are the parts of a operon? A regulatory gene. The regulatory gene codes for a regulatory protein. … An operator. The operator is the region of DNA of the operon that is the binding site
What Is An Operon And What Does It Do? Operon, genetic regulatory system found in bacteria and their viruses in which genes coding for functionally related proteins are clustered along the DNA. This feature allows protein synthesis to be controlled coordinately in response to the needs of the cell. What is the purpose of operons?
What Is The Difference Between Monocistronic And Polycistronic? Polycistronic mRNA is a mRNA that encodes several proteins and is characteristic of many bacterial and chloroplast mRNAs. Polycistronic mRNAs consist of a leader sequence which precedes the first gene. … Monocistronic mRNA is a mRNA that encodes only one protein and all eukaryotic mRNAs are monocistronic.
