Prokaryotes can coordinate the expression of genes for a specific function by grouping them into an operon, which is controlled by a single promoter. The following allows eukaryotes to have similar coordinated control over a set of genes for a specific function?
A single transcriptional regulator controlling multiple genes.
The key to coordinate gene expression in eukaryotes is often associated of a of a particular metabolic pathway that is specific combination of control sequences with every gene. Copies of the activators that recognize these control sequences bind to them all at once, promoting simultaneous transcription of the genes, no matter where they are in the genome.

Regulation of Gene Expression in Eukaryotes In eukaryotes, the Central Dogma of Genetics can be expanded to include post-transcriptional processing and post-translational processing, thus the Dogma becomes: Replication - Transcription Post-transcriptional Processing -Translation - Post-translational Processing - Functional Protein - Expressed Trait. This is the flow of information from the genetic material to the actual physical, chemical or behavioral trait in an organism. Of course, some traits are controlled by multiple genes and some also have an environmental component. At...

Which of the following mechanisms is (are) used to coordinate the expression of multiple, related genes in eukaryotic cells? a. The genes are organised into an operon, allowing them to be co-ordinately controlled as a single unit. b. The genes have enhancers with similar control elements, which allows appropriate activators to turn on their transcription at the same time. c. A single repressor is able to turn off several related genes. d. Environmental signals enter the cell and bind directly...

Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

Last week we discussed the role of general transcription factors in forming the transcription initiation complex in eukaryotes. Next week we will look more closely at the regulation of gene expression and the role played by specific transcription factors. Prokaryotes and eukaryotes utilize very different mechanisms for determining which genes are turned on and off and when. In lieu of the prokaryotic operon model, eukaryotes employ a combinatorics approach utilizing both general and specific transcription factors. For this week’s forum,...
