pseudogene[′sü·dō‚jēn] (genetics) A sequence of deoxyribonucleic acid resembling but not functioning like a gene; usually produced by gene duplication followed by mutations that alter or abolish function. pseudogeneenUK
pseu·do·gene (sū'dō-jēn), 1. A sequence of nucleotides that is not transcribed and therefore has no phenotypic effect. 2. An inactive DNA segment that arose by a mutation of a parental active gene. pseudogene (so͞o′də-jēn′)n. A segment of DNA that resembles a gene but is not functional and usually not transcribed. Pseudogenes often have functional paralogs in the same organism.pseudogene a nucleotide sequence, similar to that of a known functional gene, but that is inactive due to the accumulation of MUTATIONS. A pseudogene may result from a tandem DUPLICATION of an existing gene or REVERSE TRANSCRIPTION of the transcript of the gene (so that it lacks the introns and has a POLY(A) TAIL). |
