Results: We have developed a homology-based … Pseudogenes for RNA genes are usually more difficult to discover as they do not need to be translated and thus do not have "reading frames". Pseudogenes can complicate molecular genetic studies. For example, amplification of a gene by PCR may simultaneously amplify a pseudogene that shares similar … 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. Thus, they do not require many genes that are needed by free-living bacteria, such as gene associated … See more Pseudogenes are usually characterized by a combination of similarity to a known gene and loss of some functionality. That is, although every pseudogene has a DNA sequence that is … See more There are four main types of pseudogenes, all with distinct mechanisms of origin and characteristic features.
