What is the function of the following elements of an operon? a) regulator b) operator c) promoter d) structural genes Operon: Operon is a structure in DNA and contains multiple functional genes. Prokaryotes like bacteria and archaea contain an ...
1) What is an operon, and what kinds of cells use operons? 2) What is a repressor protein, how does it regulate the transcription of an operon (like the lac operon)? Define operon. Explain the operon with its components. What is an operon? In what type of organism would you expect...
An operon is a set of genes that are regulated together and controlled by a single promoter. This unit of genetic material consists of a promoter, operator, and structural gene(s) that are transcribed into mRNA together. Operons are commonly found in prokaryotic organisms (e.g., bacteria) ...

Assertion :- Lac opertor is present only in lac operon & it interact specifically with lac repressor only. Reason : Each operon has its specific operator & specific repressor. View Solution How are the structural genes activated in the lac operon in E. coli ?
Another example of a cis gene is the operator gene in lac operon. It when bound by the repressor molecule is unable to initiate transcription. However, when the inducer (lactose) binds to the repressor molecule inactivating it, normal transcription can occur. Share Possibly...

What does the lac operon consist of?Lac Operon:The lactose operon (also called the lac operon) is a group of genes present in E. coli and other bacteria responsible for lactose absorption and metabolism. Two proteins regulate the activity of the lac promoter, which controls the lac operon's...
Why is it important that both strands have all the information? Which of the following is not a segment of DNA? a. regulatory gene b. structural gene c. promoter d. operator e. inducer The promoter is an important sequence for transcription of a gene. Which of these components...
The Lac repressor, by contrast, binds to specific operator sites on DNA, introduces lesser distortions in the double helix [6], and interconverts between the tightly closed, V-shaped protein architecture observed in the crystalline state and an extended open form with widely separated DNA-...
