Question

Write the locations of utr in mrna and state its functions

Answer 1

The recent analysis of the human genome [1,2] and the data available about other higher eukaryotic genomes have revealed that only a small fraction of the genetic material - about 1.5% - codes for protein. Indeed, most genomic DNA is involved in the regulation of gene expression, which can be exerted at either the transcriptional level, controlling whether a gene is transcribed or not and to what extent, or the post-transcriptional level, controlling the fate of the transcribed RNA molecules, including their stability, the efficiency of their translation and their subcellular localization. This article will review the structure, functions and mechanisms of mRNA untranslated regions.
