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.
A structural gene is a gene that codes for any RNA or protein product other than a regulatory factor (i.e. regulatory protein).Structural genes are typically viewed as those containing sequences of DNA corresponding to the amino acids of a protein that will be produced, as long as said protein does not function to regulate gene expression.
The TCF7L2 gene, encoding the TCF7L2 protein, is located on chromosome 10q25.2-q25.3. The gene contains 19 exons. [7] [8] Of the 19 exons, 5 are alternative. [8]The TCF7L2 protein contains 619 amino acids and its molecular mass is 67919 Da. [26]
The untranslated regions of mRNA became a subject of study as early as the late 1970s, after the first mRNA molecule was fully sequenced. In 1978, the 5' UTR of the human gamma-globin mRNA was fully sequenced. [3]
Gene 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, proteins or non-coding RNA, and ultimately affect a phenotype.

A cistron is a region of DNA that is conceptually equivalent to some definitions of a gene, such that the terms are synonymous from certain viewpoints, [1] especially with regard to the molecular gene as contrasted with the Mendelian gene.
In 1999 it was reported that telomeres, which cap the end of chromosomes, terminate in a lariat-like structure termed a T-loop (Telomere-loop). [11] This is a loop of both strands of the chromosome which are joined to an earlier point in the double-stranded DNA by the 3' strand end invading the strand pair to form a D-loop.
