  2. Nomenclature codes - Wikipedia

    en.wikipedia.org/wiki/Nomenclature_codes

    [15] [16] The originally planned implementation date for the BioCode draft was January 1, 2000, but agreement to replace the existing Codes was not reached. In 2011, a revised BioCode was proposed that, instead of replacing the existing Codes , would provide a unified context for them, referring to them when necessary.

  3. Form W-2 - Wikipedia

    en.wikipedia.org/wiki/Form_W-2

    In US territories, the W-2 is issued with a two letter territory code, such as W-2GU for Guam. Corrections can be filed using Form W-2c. Corrections can be filed using Form W-2c. The use of the form has led to the phrase "W-2 employees" to refer to those who receive Form W-2, in contrast to independent contractors and other "1099 workers" whose ...

  4. Coding region - Wikipedia

    en.wikipedia.org/wiki/Coding_region

    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 ...

  5. Untranslated region - Wikipedia

    en.wikipedia.org/wiki/Untranslated_region

    [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 mechanism of translation initiation differs in prokaryotes and eukaryotes. The 3' UTR is found immediately following the translation stop codon.

  6. Subspecies - Wikipedia

    en.wikipedia.org/wiki/Subspecies

    A subspecies is a taxonomic rank below species – the only such rank recognized in the zoological code, [14] and one of three main ranks below species in the botanical code. [12] When geographically separate populations of a species exhibit recognizable phenotypic differences, biologists may identify these as separate subspecies; a subspecies ...

  7. Order (biology) - Wikipedia

    en.wikipedia.org/wiki/Order_(biology)

    Orders of plants, fungi, and algae use the suffix -ales (e.g. Dictyotales). [3] Orders of birds and fishes [ 4 ] use the Latin suffix -iformes meaning 'having the form of' (e.g. Passeriformes ), but orders of mammals and invertebrates are not so consistent (e.g. Artiodactyla , Actiniaria , Primates ).

  8. Circular permutation in proteins - Wikipedia

    en.wikipedia.org/wiki/Circular_permutation_in...

    The permutation by duplication mechanism for producing a circular permutation. First, a gene 1-2-3 is duplicated to form 1-2-3-1-2-3. Next, a start codon is introduced before the first domain 2 and a stop codon after the second domain 1, removing redundant sections and resulting in a circularly permuted gene 2-3-1.
