Duplicated pseudogenes

WebAlthough pseudogenes are almost as numerous as protein-coding genes (14 767, of which, 72% are processed, 24% duplicated, 1.6% duplicated, 2.4% other, and 19 957, respectively) (Gencode v38 [ 35] ), comparatively little is known about the contribution of pseudogenes to the evolution of the human genome. WebDuplicated pseudogenes arise from genomic DNA duplication or unequal crossing over. They retain the original exon–intron organization of the functional gene (hence nonprocessed), but their protein-coding potential is lost because of the loss of transcription regulatory elements, such as promoters or enhancers, or mutations disrupting the ORF ...

WebEvolution by gene duplication is an event by which a gene or part of a gene can have two identical copies that can not be distinguished from each other. This phenomenon is understood to be an important source of novelty in evolution, providing for an expanded repertoire of molecular activities. The underlying mutational event of duplication may ... WebApr 13, 2024 · Gene duplication is thought to be a central process in evolution to gain new functions. The factors that dictate gene retention following duplication as well paralog gene divergence in sequence, expression and function have been extensively studied. However, relatively little is known about the evolution of promoter regions of gene duplicates and … WebJun 11, 2024 · Pseudogenes are defective copies of functional genes. These may be partial or complete duplicates derived from polypeptide-encoding genes or RNA genes. The DNA sequence of a pseudogene is characteristically very similar to its functional counterpart, but contains variant mutations that render the gene inactive. cholesterol transport in cells
