Gene expression is the term for the process of a cell making a protein based on the directions of a gene. Gene expression occurs in all forms of life.
Well, prokaryotic cells are not really part of the body. A prokaryotic cell is pretty much the same as Bacteria. Are we made of Bacteria? No, we have bacteria in us but we are not made of Bacteria. The above statement is true. But! While Bacteria are prokaryotes, the reverse is not true. Archean cells are also prokaryotic. And! We actually have more prokaryotic cells in and on us then eukaryotic cells.
In prokaryotes, gene expression can be regulated directly at the level of transcription through operons, where multiple genes are controlled by a single promoter. This type of regulation is not as common in eukaryotes, where gene expression is typically regulated at multiple levels, including transcription, RNA processing, translation, and post-translational modifications. Additionally, prokaryotes lack the complexity of chromatin structure found in eukaryotic cells, which can also impact gene expression regulation.
Gene expression is the process by which inheritable information from a gene, such as the DNA sequence, is made into a functional gene product, such as protein or RNA.
Transcription in prokaryotic cells begins when RNA polymerase binds to the promoter region of a gene. This binding allows RNA polymerase to start synthesizing mRNA based on the DNA template strand. The initiation of transcription is a critical step that involves recognizing specific DNA sequences and recruiting necessary factors for gene expression.
Analogous to the brain, the nucleoid region in a prokaryotic cell contains the genetic material (DNA) in a condensed form. This region functions similar to the brain as it controls all cellular activities by regulating gene expression and protein synthesis.
An operon is a cluster of genes under the control of a single promoter in prokaryotic cells. They are typically found in bacteria and archaea, where they allow for coordinated regulation of gene expression by sharing regulatory elements.
Enhancers bind to specific regions of DNA within the cell to regulate gene expression.
Gene expression is the term for the process of a cell making a protein based on the directions of a gene. Gene expression occurs in all forms of life.
Gene expression is the activation of a gene that results in the formation of a protein.
Transcription takes place in the nucleus of a cell during the process of gene expression.
Transcription factors bind to specific DNA sequences within the cell's nucleus to regulate gene expression.
Actually, for some uses prokaryotic cells are just fine for eukaryotic gene expression. That said bacteria are deficient in quite a lot of the post-translational modification systems that eukaryotes use, such as glycosylation. Since those post-translational modifications can actually be important to the protein's function you might choose a eukaryotic expression system to preserve them.

In prokaryotes, the regulatory region of a gene where transcription factors bind to enhance gene expression is called the promoter region. While prokaryotes do not have enhancer regions like eukaryotes, they can have operator regions where repressor proteins bind to downregulate gene expression.
