How is gene expression a regulated process

WebThe expression of a gene is a highly regulated process. In multicellular organisms it allows for cellular differentiation, in single-celled organisms like prokaryotes, it primarily ensures that a cell’s resources are not wasted making proteins that the cell does not need at that time. Elucidating the mechanisms controlling gene expression is ...

WebA. two moles of water are formed for each mole of methane consumed. B. two molecules of oxygen are consumed per one molecule of methane consumed. C. the combined mass of the reactants equals the combined mass of the products. D. two grams of oxygen are consumed for each gram of carbon dioxide formed. WebPost-Transcriptional Events of Gene Expression Whereas the initial transcript of a bacterial gene is the a ctual messenger RNA, the initial transcript of a eukaryotic gene must be altered in a variety of ways before it can function. Thus, post-transcriptional processing and modification events are critical to the formation of a eukaryotic mRNA. teamviewer for chrome remote desktop https://ecolindo.net

What is gene expression and how does it work? [Fact Checked!]

WebGenes in an operon are transcribed as a group and have a single promoter. Each operon contains regulatory DNA sequences, which act as binding sites for regulatory proteins that promote or inhibit transcription. Regulatory proteins often bind to small molecules, which can make the protein active or inactive by changing its ability to bind DNA. WebGene regulation is the process of turning genes on or off. Gene regulation can occur at any point of the transcription-translation process but most often occurs at the transcription...
