Control of gene expression in prokaryotes pogil answers. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then ...

Prokaryotic Gene Regulation. In bacteria and archaea, structural proteins with related functions are usually encoded together within the genome in a block called an operon and are transcribed together under the control of a single promoter, resulting in the formation of a polycistronic transcript (Figure 1).

Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.

A corepressor is, by definition, In the field of molecular biology, "a substance that inhibits the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins." In the case of E. coli, the corepressor is the Tryptophan. question. What is Gene Expression?Gene expression is the process by which genetic information encoded in DNA is used to produce proteins and other molecules. It is the fundamental process by which genetic information is translated into biological products like proteins and RNA. Prokaryotes, or bacteria, are single-celled organisms that lack a nucleus and other membrane-bound organelles.Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA. Often, these molecules act by binding to DNA near the gene and helping or blocking the transcription enzyme, RNA polymerase. Let's take a closer look at how genes are regulated in bacteria.
