WebIn prokaryotes, structural genes of related function are often organized together on the genome and transcribed together under the control of a single promoter. The operon’s regulatory region includes both the promoter and the operator. If a repressor binds to the operator, then the structural genes will not be transcribed. WebGenes that are expressed usually have introns that interrupt the coding sequences. A typical eukaryotic gene, therefore, consists of a set of sequences that appear in mature mRNA (called exons) interrupted by introns. The regions between genes are likewise not expressed, but may help with chromatin assembly, contain promoters, and so forth.

In some living things, there are stretches of DNA between genes. These stretches are called “non-coding DNA,” because they don’t code for proteins. In humans, about 98% of our DNA is non-coding. how get sweat stains out of shirts
