The lac operon which facilitates or enables lactose digestion to take place has three adjacent structural genes. These genes include lacZ, lacY and lacA. They all have their own unique purpose.

Is operon the sequence of bases on a gene that does not code for protein?
operon is a group of genes regulated by a single promoter and operator. . . generally all the genes (structural genes of a particular operon) regulate a specific metabolic pathway. . (eg : lac operon in bacteria; where 3 genes are regulated by a single promoter sequece which help in the catabolism of lactose). . . if you have any doubts mail me at vegi.chaitanya@gmial.com
What is the function of an operator in bacteria?
The function of an operator in bacteria can be defined as the required for the transport and metabolism of the lactose in Escherichia coli and some other enteric bacteria. It consist of three adjacent structural genes.
What is the difference between an operon and a regulon?
1. For operon genes are located near each other. For regulon genes are present distinct site of DNA. 2. Operon may have specific operator for all genes. For regulon each gene have different operator.
When a group of gene pairs act together?
A group of genes that is operated together is an Operon.
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
The regulation of gene expression allows prokaryotic cells, such as bacteria, to better respond to stimuli and to conserve energy and materials
Transcription of the structural genes in an inducible operon?
starts when the pathway's substrate is present

An operon is composed of?
An operon is a group of genes that operate together.Operon- a functioning unit of genomic DNA containing a cluster of genes under the control of a single regulatory signal or promoter.Operons are clusters of genes consisting of one operator and promoter. There are a lac operon, which is responsible for metabolism of glucose. And there is also the Trp operon, which is responsible for synthesising tryptophan.
What is the function of an operator in bacteria?
The function of an operator in bacteria can be defined as the required for the transport and metabolism of the lactose in Escherichia coli and some other enteric bacteria. It consist of three adjacent structural genes.
The operon segment composed of the gene that codes for a protein repressor is called the?
The operon segment composed of the gene that codes for a protein repressor is called the regulatory gene. This gene produces the repressor protein that can bind to the operator region of the operon, preventing transcription of the structural genes when the repressor is bound.
Group of genes that work together?
Operon
In Figure 84 which model of the lac operon correctly shows RNA polymerase lactose and repressor protein when the structural genes are being transcribed?
regulatory promoter oerator
What is the difference between an operon and a regulon?
1. For operon genes are located near each other. For regulon genes are present distinct site of DNA. 2. Operon may have specific operator for all genes. For regulon each gene have different operator.
What name is given to a cluster of genes with related functions along with their control sequences in bacteria?
An inducer is a cluster of genes that codes for proteins with related functions. They do this by disabling repressors, which causes the gene to be expressed.
What genes is not a part of the lac operon?
repressor gene
What are the three components of an operon and there roles?
Holy crud, are you in AP Biology too?Anyway... take the trp operon, for instance. Its components are...Five Structural Genes:These genes contain the genetic code for the five enzymes in the Trp synthesis pathwayOne Promoter:DNA segment where RNA polymerase binds and starts transcriptionOne Operator:DNA segment found between the promoter and structural genes. It determines if transcription will take place. If the operator is turned "on", transcription will occur.
What controls the transcription of prokaryotic genes?
The operon often controls the transcription of prokaryote genes.
