WebThere are many steps along the way of protein synthesis and gene expression is regulated. Gene expression is when a gene in DNA is “turned on,” that is, used to make the protein it specifies. Not all the genes in your body are turned on at the same time or in the same cells or parts of the body. WebGene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.

"WebThe five genes that are needed to synthesize tryptophan in E. coli are located next to each other in the trp operon. When tryptophan is plentiful, two tryptophan molecules bind the repressor protein at the operator sequence. This physically blocks the RNA polymerase from transcribing the tryptophan genes.
