Herein, what are the components of an operon?
An operon is made up of 3 basic DNA components:
- Promoter – a nucleotide sequence that enables a gene to be transcribed.
- Operator – a segment of DNA to which a repressor binds.
- Structural genes – the genes that are co-regulated by the operon.
One may also ask, how many structural genes are found in Lac operon? three structural genes
Also to know, what are the two types of operons?
Operons are of two types, inducible and repressible. ADVERTISEMENTS: Inducible Operon System – Lac Operon (Fig 6.34): An inducible operon system is a regulated unit of genetic material which is switched on in response to the presence of a chemical.
How are the expressed genes of an operon usually arranged?
A. The expressed genes are located one by one after the regulatory region of the operon. The expressed genes are located one by one before the regulatory region of the operon.
