Regulatory proteins turn on or off gene expression by binding to specific regions of DNA called promoters or enhancers. They can either activate or repress the transcription of genes by recruiting other proteins that help modify the chromatin structure or by directly interacting with the RNA polymerase complex.

Can regulatory proteins exert their effects?

Yes, they would be of no use if they could not. Regulatory proteins use four ways to exert their effects.


Do proteins have both structural and regulatory functions in the body?

they have have structural, defense and regulatory functions


What are the combinations of active or inactive regulatory proteins that could be present at any time in a prokaryotes cell?

In prokaryotic cells, regulatory proteins can exist in active or inactive forms, influencing gene expression. The combinations of these proteins include active regulatory proteins (such as activators), inactive regulatory proteins (like repressors), and various interactions among them, such as an active repressor that can become inactive in the presence of an inducer. Additionally, the presence of co-activators or co-repressors can further modulate these states, leading to a dynamic regulatory landscape that allows for precise control of gene expression in response to environmental changes.


What is the name of the regulatory protein?

There are many regulatory proteins in the human body, such as transcription factors, kinases, and G-proteins. It would depend on the specific context or system you are referring to in order to determine the name of the regulatory protein.


What do prokaryotic and eukaryotic cells use to turn certain genes on or off?

Prokaryotic cells use regulatory proteins like repressors or activators that bind to the DNA to turn genes on or off. Eukaryotic cells use a combination of transcription factors, chromatin remodeling complexes, and non-coding RNAs to regulate gene expression.

Difference between inducible and repressible operons?

Inducible operons are normally turned off but can be turned on by an inducer molecule, such as lactose in the lac operon. Repressible operons are typically turned on but can be turned off by a corepressor molecule, like tryptophan in the trp operon. The key difference is in their default state and the signal that controls their activity.

What are genes that are turned off called?

The genes are controlled by the control elements in their upstream sequence. It can also regulated at RNA level by si, sh RNAs. The regulation is basically influenced by the surrounding environments. Proteins mediated the regulation of gene expression.


What do the regulatory regions found in a chromosome primarily regulate?

Regulatory regions in a chromosome primarily regulate gene expression. By interacting with specific proteins and other regulatory elements, these regions can influence when and how genes are transcribed into RNA, ultimately affecting the production of proteins in a cell.
