What else can I help you with?
The term operon comes from the latin root word?
The term operon comes from the Latin word "operare," which means to work or function. In molecular biology, an operon refers to a functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter.
What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
What is the term that refers to a contiguous genetic complex that is under coordinate control?
The term that refers to a contiguous genetic complex that is under coordinate control is "operon." It consists of a promoter, operator, and structural genes that function together in prokaryotic cells to regulate gene expression.
How does the active CAP induce expression of the genes of the lactose operon?
The active CAP (catabolite activator protein) binds to the CAP site near the promoter of the lactose operon. This binding helps RNA polymerase bind to the promoter, leading to enhanced transcription of the genes in the lactose operon. This process is a part of positive regulation in response to low glucose levels and presence of lactose.
Is operon proteins?
Operon is not a protein. It is a segment of DNA that has cluster of genes controlled by the elements such as promoter, operator. Lac operon is a classic example where it regulate the utilization of Lactose in the medium.
In bacteria a group of genes that code for functionally related enzymestheir promoter site and the operator that controls them all function together as an?
operon. An operon is a unit of bacterial gene expression consisting of a promoter, an operator, and a cluster of genes that work together as a single transcriptional unit. The operator region controls the transcription of the genes within the operon in response to regulatory signals.
How many promoters are there in the entire operon?
An operon typically has one promoter, which initiates the transcription of the genes within the operon.
What is a collective name for a group of genes involved in the same function their promoter site and their operator?
The collective name for a group of genes involved in the same function, along with their promoter site and operator, is known as an operon. Operons in prokaryotic cells allow coordinated regulation of gene expression by controlling transcription of multiple genes as a single unit.
How does the repressor protien prevent transcription?
it blocks the promoter from the operon.
The term operon comes from the latin root word?
The term operon comes from the Latin word "operare," which means to work or function. In molecular biology, an operon refers to a functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter.
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 does the promoter of the lac operon sac do?
The promoter of the lac operon helps initiate the transcription of the lac genes. It is where RNA polymerase binds to start transcribing the mRNA for the lacZ, lacY, and lacA genes. The Lac operon is a system in bacterial cells that regulates the expression of genes involved in lactose metabolism.
Four of the five answers listed below are features of the lactose operon Select the exception a regulator b terminator c operator d promoter e structural gene?
The "lac operon" is the unit of DNA in E.coli and other bacteria which is responsible for the metabolism of lactose. So with regards to the question above, its function is that of an operator.
What is promoters and an operator together called?
Operon. It contains the promoter, operator, and the structural gene.
What is the term that refers to a contiguous genetic complex that is under coordinate control?
The term that refers to a contiguous genetic complex that is under coordinate control is "operon." It consists of a promoter, operator, and structural genes that function together in prokaryotic cells to regulate gene expression.
