WebJun 23, 2011 · Duplicated pseudogenes are the largest class. Scientists posit that these DNA segments arose when gene (s) underwent duplication in the genome, after which the duplicated copies experienced severe mutations, rendering them unrecognizable as a functional gene by the cell’s machinery. WebNov 1, 2024 · Duplicated pseudogenes, which have intron–exon-like gene structures, may retain upstream regulatory elements of their parent genes, resulting in a stronger positive correlation with the parent gene and more active transcription than retroposed pseudogenes [9].
