The promoter allows the gene to be transcribed. It helps RNA polymerase find where a gene starts. An operator is a DNA segment that turns the gene "on" or "off." It interacts with proteins that increase the rate of transcription or block transcription from occurring.

In the control of gene expression in bacteria a regulatory gene a has its own promoter?
No
What can sometimes influence expression of genes?
Several factors determine the final outcome of gene expression. They include the cell's environment, the presence of other cells, and the timing of gene expression. hope this helped! -Steph
What does the operon model attempt explain?
the coordinated control of gene expression in bacteria
What is the common control point of gene expression for all organisms?
cell membrane
What best describes gene expression?
Proteins are made only at certain times in certain cells.
Can eukaryotic Cells control gene expression by using transcription factors?
yes
The snipping out of specific introns for troponin production by muscle cells is an example of what type of gene expression control?
transcript processing
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.
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
No
Benefits of medical treatments that control gene expression?
I would guess that if a gene is not functioning normally then controlling the expression of that gene would be beneficial.
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.
What does differential gene expression mean?
The process by which different cells express different genes depending on their needs is called differential gene expression
What is involved in regulating gene expression in prokaryotes but not in eukaryotes?
The regulation of gene expression allows prokaryotic cells, such as bacteria, to better respond to stimuli and to conserve energy and materials
What can sometimes influence expression of genes?
Several factors determine the final outcome of gene expression. They include the cell's environment, the presence of other cells, and the timing of gene expression. hope this helped! -Steph
What is it called when sections of chromosomes control genes?
regulation of gene expression
What can plant hormones be characterized by?
They may act by altering gene expression. They have a multiplicity of effects. They control plant growth and development and they affect division, elongation and differentiation of cells.
What does the operon model attempt explain?
the coordinated control of gene expression in bacteria
