Protein synthesis and gene regulation
Did you know?
WebbBecause proteins are coded by genes, the term “gene expression” refers to protein synthesis (i.e., making proteins), including the regulation of that synthesis. There are two main processes that must occur to synthesize proteins: transcription and translation. WebbThe synthesis of the protein is modeled as a single reaction. Gene Repression. Transcription of DNA to mRNA is regulated by the binding of the protein product from …

WebbThis tRNA is brought to the 40S ribosome by a protein initiation factor, eukaryotic initiation factor-2 (eIF-2). The eIF-2 protein binds to the high-energy molecule guanosine triphosphate (GTP). The tRNA-eIF2-GTP complex then binds to the 40S ribosome. A second complex forms on the mRNA. Several different initiation factors recognize the 5' cap ... WebbRegulation of Gene Expression. Figure 17.1 The genetic content of each somatic cell in an organism is the same, but not all genes are expressed in every cell. The control of which genes are expressed dictates whether a cell is (a) an eye cell or (b) a liver cell. It is the differential gene expression patterns that arise in different cells that ...

Regulation of gene expression adjusts protein synthesis and, in turn, cellular growth. Messenger RNAs are key … black overcoat with hoodWebbGene expression involves transcription of genes into mRNAs followed by translation of mRNAs into proteins. Protein concentrations are in turn determined by the balance between protein synthesis and dilution ( Fig. 1A and fig.
