Gene Expression in ProkaryotesGene Regulation/ trp operon
How Is Gene Expression Increased or Decreased in Response to Environmental Change? In prokaryotes, regulatory proteins are often controlled by nutrient availability. This allows organisms such as bacteria to rapidly adjust their transcription patterns in response to environmental conditions. In addition, re...
In prokaryotes, the main site for regulation of gene expression is transcription initiation. Within a transcription unit, the activity of RNA polymerase at the promoter is regulated by ‘accessory proteins’. These proteins affect the ability of RNA polymerase to recognize start sites. These proteins...

Gene expression in prokaryotes as well as in eukaryotes is regulated quantitatively and qualitatively by specific upstream DNA sequences.1These DNA sequences are commonly known as gene promoters. Initiation of transcription is in turn mediated by proteins that recognize specific DNA sequences in the ...
In subject area: Biochemistry, Genetics and Molecular Biology Gene expression systems can be designed to control the rate of transcription from transgene and efficiency of mRNA processing as well as the half life of the mRNA within the cell. ...
DNA is found as a single circularchromosomein thecytoplasm. Some prokaryotes, such asbacteria, and a few eukaryotes have extrachromosomal DNA known asplasmids, which areautonomous, self-replicating genetic material. Plasmids have been used extensively inrecombinant DNA technologyto study gene expression....

After the expression of specific genes in a set of cells are switched on by a signal, these genes may have to remain switched on for many cell generations, even if the signal that induced them is present only fleetingly (飞快地). The inheritance of gene expression patterns, in the absence...
