  2. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Top: An ancestral gene duplication produces two paralogs (histone H1.1 and 1.2). A speciation event produces orthologs in the two daughter species (human and chimpanzee). Bottom: in a separate species , a gene has a similar function (histone-like nucleoid-structuring protein) but has a separate evolutionary origin and so is an analog.

  3. Homology (biology) - Wikipedia

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

    The term "ortholog" was coined in 1970 by the molecular evolutionist Walter Fitch. [41] Homologous sequences are paralogous if they were created by a duplication event within the genome. For gene duplication events, if a gene in an organism is duplicated, the two copies are paralogous. They can shape the structure of whole genomes and thus ...

    A speciation event produces orthologs in the two daughter species (human and chimpanzee). Bottom: in a separate species ( E. coli ), an gene has a similar function ( histone-like nucleoid-structuring protein ) but has a separate evolutionary origin and so is an analog .

    English: Top: An ancestral gene duplicates to produce two paralogs (Genes A and B). A speciation event produces orthologs in the two daughter species. Bottom: in a separate species, an unrelated gene has a similar function (Gene C) but has a separate evolutionary origin and so is an analog.

  6. EVA1C - Wikipedia

    en.wikipedia.org/wiki/EVA1C

    The paralogs of EVA1C are EVA1A (Eva-1 Homolog A) and EVA1B (Eva-1 Homolog B). [17] [18] The thorny skate (Amblyraja radiata) was found to be the most distant ortholog in EVA1A, EVA1B, and EVA1C. [14] [19] [20] The divergence time of humans and the thorny skate is 464 million years ago. [16]

    An updated wedding guest scoring system spreadsheet entitled "Don't Give a Sheet" is available for purchase on Shopify because they "broke Etsy." Now, maybe O'Malley and O'Neill will be able to ...

  8. Gene nomenclature - Wikipedia

    en.wikipedia.org/wiki/Gene_nomenclature

    Some basic conventions, such as (1) that animal/human homolog (ortholog) pairs differ in letter case (title case and all caps, respectively) and (2) that the symbol is italicized when referring to the gene but nonitalic when referring to the protein, are often not followed by contributors to medical journals.
