Related to pseudogene: Synonymous substitution, Genome duplication
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.
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.
Etymology: Gk, pseudes + genein, to produce
a DNA sequence that resembles a gene and may be derived from one but lacks a genetic function.
pseudogenea 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).
a nonfunctional DNA sequence, nearly homologous to a functional gene.
