Transcription of an inducible enzyme is triggered by the presence of specific substrates or signals that activate transcription factors. These factors bind to promoter regions of the gene encoding the enzyme, facilitating the recruitment of RNA polymerase. This process often involves the removal of repressive elements or the binding of activators that enhance gene expression in response to environmental changes. As a result, the enzyme is produced only when needed, allowing for efficient metabolic regulation.
What else can I help you with?
What does synthesis of an inducible enzyme require?
The synthesis of an inducible enzyme requires the presence of specific substrates or signals that trigger gene expression. This process typically involves the binding of an inducer molecule to a regulatory protein, which then activates the transcription of the gene encoding the enzyme. Additionally, cellular mechanisms such as transcription factors and RNA polymerase play crucial roles in facilitating the transcription and subsequent translation of the enzyme. Overall, the process ensures that the enzyme is produced only when needed, allowing for efficient metabolic regulation.
Enzymes that are produced only when substrate is present are termed?
induced enzyme
What major enzyme is involved in transcription?
A u g
What enzyme aids in the process of transcription?
RNA polymerase
What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.

What molecule causes transcription of an operon?
The molecule that typically causes transcription of an operon is an inducer, which can either activate or repress the operon by binding to a regulatory protein. In the case of an inducible operon like the lac operon in E. coli, lactose acts as an inducer by binding to the repressor protein and preventing it from blocking transcription.
Synthesis of an inducible enzyme requires?
Substrate bound to a repressor Chris G.
What is the enzyme that catalyzes transcription?
The enzyme that catalyzes transcription is called RNA polymerase.
Enzymes that are produced only when substrate is present are termed?
induced enzyme
What enzyme catalyzes transcription in cells?
The enzyme that catalyzes transcription in cells is called RNA polymerase.
Which enzyme binds to DNA during transcription?
RNA polymerase is the enzyme that binds to DNA during transcription.
Transcription of the structural genes in an inducible operon?
In an inducible operon, the structural genes are transcribed only when an inducer molecule is present. The inducer molecule binds to the repressor protein, causing it to be released from the operator region. This allows the RNA polymerase to bind to the promoter region and initiate transcription of the structural genes.
Which enzyme is responsible for reading DNA during transcription?
The enzyme responsible for reading DNA during transcription is called RNA polymerase.
What enzyme is used in reverse transcription?
Reverse transcriptase is the enzyme used in reverse transcription to generate complementary DNA (cDNA) from an RNA template.
How does the transcription helicase enzyme facilitate the unwinding of DNA during the transcription process?
The transcription helicase enzyme helps to unwind the double-stranded DNA by breaking the hydrogen bonds between the two strands. This allows the RNA polymerase enzyme to access the DNA template and create a complementary RNA strand during the transcription process.
The enzyme that adds and links complementary RNA nucleotides during transcription is called?
RNA polymerase is the enzyme that adds and links complementary RNA nucleotides during transcription
