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. Most arise as superfluous copies of functional genes, either directly by gene duplication or indirectly by reverse transcription of … See more While the vast majority of pseudogenes have lost their function, some cases have emerged in which a pseudogene either re-gained its original or a similar function or evolved a new … See more Pseudogenes are found in bacteria. Most are found in bacteria that are not free-living; that is, they are either symbionts or obligate intracellular parasites. Thus, they do not require … See more Pseudogenes are usually characterized by a combination of similarity to a known gene and loss of some functionality. That is, although every … See more There are four main types of pseudogenes, all with distinct mechanisms of origin and characteristic features.

WebThe selective binding by the population of microRNAs explains the role that duplicated pseudogenes play in regulating gene expression. The sequence similarity between the duplicated pseudogene and the corresponding “intact” gene means that the same microRNAs will bind to both mRNA transcripts.
