At least 15% of pseudogenes are transcriptionally … The classic example of a unitary pseudogene is the gene that presumably coded the enzyme L-gulono-γ-lactone oxidase (GULO) in primates. In all mammals studied besides primates (except guinea pigs), GULO aids in the biosynthesis of ascorbic acid (vitamin C), but it exists as a disabled gene (GULOP) in humans … 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 function. Examples include the following: Drosophila … 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.
