Duplicated pseudogenes

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 ... WebJul 2, 2008 · Background Pseudogenes, nonfunctional copies of genes, evolve fast due the lack of evolutionary pressures and thus appear in several different forms.

WebJul 8, 2010 · Duplicated pseudogenes are formed when the new sequence undergoes mutations that result in the loss of original function. In contrast, processed pseudogenes arise from retrotransposition events [typically indicated by the lack of introns and presence of a 3′-poly(A) tail] (7, 8). They usually lack promoter sequences, and hence are considered ... Duplicated pseudogenes usually have all the same characteristics as genes, including an intact exon-intron structure and regulatory sequences. The loss of a duplicated gene's functionality usually has little effect on an organism's fitness, since an intact functional copy still exists. See more Pseudogenes are nonfunctional segments of DNA that resemble functional genes.
