What Transcription of lactose metabolizing genes is blocked?
The transcription of lactose metabolizing genes, specifically the genes involved in the lac operon (such as lacZ, lacY, and lacA), is blocked in the presence of glucose. This phenomenon is known as catabolite repression, where the presence of glucose inhibits the synthesis of cyclic AMP (cAMP). Low levels of cAMP result in reduced binding of the cAMP-CRP complex to the promoter region of the lac operon, preventing the transcription of lactose-utilizing enzymes. Consequently, the cell prioritizes glucose metabolism over lactose when both sugars are available.
What is the correct order from genes to protein?
The correct order from genes to protein is: DNA (genes) -> transcription -> mRNA -> translation -> protein. During transcription, the DNA sequence is copied into mRNA, which is then translated into a protein at the ribosome.
What is the study of transcription called?
The study of transcription is called transcriptional regulation. It involves understanding how genes are transcribed into RNA molecules, which can then be translated into proteins. Researchers study factors that influence transcription, such as transcription factors, promoters, and enhancers.
Regulatory proteins in eukaryotes that are involved in controlling the onset of transcription are called?
Transcription factors are regulatory proteins in eukaryotes that control the initiation of transcription by binding to specific DNA sequences near genes and either activating or repressing their transcription. This binding helps regulate the expression of genes by influencing the binding of RNA polymerase to the promoter region of a gene.
Transcription factors function in the expression of Genes by what?
Transcription factors function in gene expression by binding to specific DNA sequences near genes, thereby regulating the transcription process. They can act as activators, enhancing the recruitment of RNA polymerase and promoting gene expression, or as repressors, inhibiting transcription. Additionally, they often respond to various cellular signals, allowing for precise control over gene expression in response to environmental changes or developmental cues. Through these mechanisms, transcription factors play a crucial role in determining when and how genes are expressed.
What controls the transcription of prokaryotic genes?
The operon often controls the transcription of prokaryote genes.

The transcription and translation of genes into proteins is called?
encoding.
Which is true of transcription factors?
They control which genes are expressed.
What is the role of transcription factors in regulating gene expression by binding to enhancers?
Transcription factors are proteins that control the activity of genes by binding to enhancers, which are specific DNA sequences that enhance gene expression. By binding to enhancers, transcription factors can either activate or repress the transcription of genes, thereby regulating gene expression.
What role do enhancers play in the process of transcription?
Enhancers are DNA sequences that can increase the rate of transcription by helping to activate specific genes. They do this by binding to transcription factors, which then interact with the RNA polymerase enzyme to initiate transcription. In this way, enhancers play a crucial role in regulating gene expression and determining which genes are transcribed in a cell.
Do transcription factors bind to enhancers to regulate gene expression?
Yes, transcription factors bind to enhancers to regulate gene expression by controlling the rate of transcription of specific genes.
Why do promoters need to be transferred along with desired genes in gene technology?
to ensure the genes are identical
