"The structure of a eukaryotic protein-coding gene. Regulatory sequence controls when and where expression occurs for the protein coding region (red). Promoter and enhancer regions (yellow) regulate the transcription of the gene into a pre-mRNA which is modified to add a 5' cap and poly-A tail (grey) and remove introns.
Gene structure is the organisation of specialised sequence elements within a gene. Genes contain most of the information necessary for living cells to survive and reproduce. [ 1 ] [ 2 ] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.

The structure of a eukaryotic protein-coding gene. Regulatory sequence controls when and where expression occurs for the protein coding region (red). Promoter and enhancer regions (yellow) regulate the transcription of the gene into a pre-mRNA which is modified to remove introns (light grey) and add a 5' cap and poly-A tail (dark grey).
The diagram labels a region of only 55 or so bases as a gene. In reality, most genes are hundreds of times larger. An internal control region is a sequence of DNA located with the coding region of eukaryotic genes that binds regulatory elements such as activators or repressors. This region can recruit RNA Polymerase or contribute to splicing.
The coding region of a gene, also known as the coding DNA sequence (CDS), is the portion of a gene's DNA or RNA that codes for a protein. [1] Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene ...
DNA gene structure of a eukaryote. In genetics, a silencer is a DNA sequence capable of binding transcription regulation factors, called repressors.DNA contains genes and provides the template to produce messenger RNA (mRNA).
Regulation of gene transcription, epigenetic regulation: Eukaryotes: MicroRNA: miRNA: Gene regulation: Most eukaryotes [14] Piwi-interacting RNA: piRNA: Transposon defense, maybe other functions: Most animals [15] [16] Small interfering RNA: siRNA: Gene regulation: Most eukaryotes [17] Short hairpin RNA: shRNA: Gene regulation: Most eukaryotes ...
