What term signifies when a cell makes a protein under the directions of a gene?
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.
Why is nucleus the most important part of the prokaryotic cell?
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.
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
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.
What is the gene expression?
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.
When does transcription begins prokaryotic cell?
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.
What is an analogy in prokaryotic cell?
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.
What is an operon and in what type of cell would they be found?
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.
Where do enhancers bind within the cell to regulate gene expression?
Enhancers bind to specific regions of DNA within the cell to regulate gene expression.
What term signifies when a cell makes a protein under the directions of a gene?
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.
Through gene expression the messages encoded in the DNA contained in a cell direct the cells activity Which of the following sentences best defines gene expression?
Gene expression is the activation of a gene that results in the formation of a protein.
Where does transcription take place in the process of gene expression?
Transcription takes place in the nucleus of a cell during the process of gene expression.
Where does the transcription factor bind within the cell to regulate gene expression?
Transcription factors bind to specific DNA sequences within the cell's nucleus to regulate gene expression.
Why prokaryotic cells are not prefer for eukaryotic 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.
Why is nucleus the most important part of the prokaryotic cell?

We actually have more prokaryotic cells in and on us then eukaryotic cells.
What region of prokaryotic gene is analogous to the enhancer region of a eukaryotic gene?
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.
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
