Scientists use a number of methods to study the complex structures and functions of the 3′ UTR. Even if a given 3′-UTR in an mRNA is shown to be present in a tissue, the effects of localization, functional half-life, translational efficiency, and trans-acting elements must be determined to understand the 3′-UTR's full functionality.

The 5′ untranslated region (also known as 5′ UTR, leader sequence, transcript leader, or leader RNA) is the region of a messenger RNA (mRNA) that is directly upstream from the initiation codon. This region is important for the regulation of translation of a transcript by differing mechanisms in viruses , prokaryotes and eukaryotes .
Although they are called untranslated regions, and do not form the protein-coding region of the gene, uORFs located within the 5' UTR can be translated into peptides. [1] The 5' UTR is upstream from the coding sequence. Within the 5' UTR is a sequence that is recognized by the ribosome which allows the ribosome to bind and initiate translation.
The Atlas of UTR Regulatory Activity (AURA), [1] a biological database, now at its second version, [2] is a manually curated and comprehensive catalog of human 5' and 3' untranslated sequences (UTR) and UTR regulatory annotations. It includes basic annotation, phylogenetic conservation, binding sites for RNA-binding proteins and miRNA, cis ...

However, the LEI code length of 20 characters represented a problem for many systems, which in practice limited the usable prefix length to 10 characters. In June 2013, ISDA working groups suggested that the characters 7 through 16 of the 20 character global LEI number should be used as the UTI prefix. This would have led to clashes between ...
It is a unique ID number or code assigned to a package or parcel. The tracking number is typically printed on the shipping label as a bar code that can be scanned by anyone with a bar code reader or smartphone. In the United States, some of the carriers using tracking numbers include UPS, [1] FedEx, [2] and the United States Postal Service. [3]
