Are promoters cis or trans-acting in gene regulation?

Promoters are cis-acting in gene regulation.


What is the definition of constitutive gene expression and how does it differ from other types of gene regulation?

Constitutive gene expression refers to genes that are constantly active and produce proteins at a steady rate in a cell. This type of gene expression is not influenced by external factors or signals. In contrast, other types of gene regulation involve genes that are turned on or off in response to specific signals or conditions in the cell's environment.


Where might one go to learn more about gene regulation?

Wikipedia has many articles on the subject of gene regulation. One could also borrow or look up gene regulation in text books from their local library. Many university professors also post their lectures and notes on gene regulation online for everyone to view.


What is the difference between a repressor and an activator in gene regulation?

In gene regulation, a repressor is a protein that blocks the expression of a gene, while an activator is a protein that enhances the expression of a gene. Repressors prevent the binding of RNA polymerase to the gene, while activators help RNA polymerase bind to the gene and initiate transcription.

Who was the operon model of the regulation of gene expression in bacteria was proposed by?

The operon model of gene regulation in bacteria was proposed by François Jacob and Jacques Monod in 1961. They introduced the concept of operons, which are clusters of genes with related functions that are regulated together. This model has since become fundamental to our understanding of gene regulation in prokaryotic organisms.

What is the tandem definition in biology and how does it relate to the concept of gene expression?

In biology, the tandem definition refers to genes that are located close together on a chromosome and are often expressed together. This proximity can influence the regulation of gene expression, as genes in tandem may be co-regulated or have similar functions. This relationship can impact how these genes are transcribed and translated into proteins, ultimately affecting the overall gene expression profile of an organism.

What is the function of the 5' UTR promoter in gene expression regulation?

The 5' UTR promoter in gene expression regulation helps to initiate the process of transcription, which is the first step in making a protein from a gene. It signals the start of transcription and helps regulate the amount of protein that is produced from that gene.


How do enhancers increase transcription in gene regulation?

Enhancers increase transcription in gene regulation by binding to specific transcription factors, which then interact with the promoter region of a gene. This interaction helps to recruit RNA polymerase and other transcriptional machinery, leading to an increase in the rate of transcription of that gene.
