Duplicated pseudogenes
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. WebNov 30, 2010 · Processed and duplicated pseudogenes are distinguished by the structure and genomic context: processed pseudogenes often are franked by genomic sequences that are different to the parent gene and usually possess a A-rich “tail” at the 3′end; duplicated pseudogenes are usually franked by genomic sequences that are almost …

In cows, the pancreatic ribonuclease gene has a paralogous gene called the seminal ribonuclease gene, which is expressed in semen. These two genes are the result of gene duplication that ... 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 ...
