Molecular genetics
Molecular genetics is the field of biology and genetics that studies the structure and function of genes at a molecular level. The field studies how the genes are transferred from generation to generation. Molecular genetics employs the methods of genetics and molecular biology...
, an untranslated region (or UTR) refers to either of two sections on each side of a coding sequence on a strand of mRNA. If it is found on the 5' side, it is called the 5' UTR
Five prime untranslated region
A messenger ribonucleic acid molecule codes for a protein through translation. The mRNA also contains regions that are not translated: in eukaryotes these include the 5' untranslated region, 3' untranslated region, 5' cap and poly-A tail....
(or leader sequence), or if it is found on the 3' side, it is called the 3' UTR
Three prime untranslated region
In molecular genetics, the three prime untranslated region is a particular section of messenger RNA . It is preceeded by the coding region....
(or trailer sequence).
