近年来,在某些真核基因结构的研究中,发现了与一个功能基因紧密毗连的一段DNA序列,它与其对应的功能基因在核苷酸序列上有明显的同源性,但又有各种各样的突变而使其不能表达,这样的一段DNA序列被称为“假基因”(Pseudogene)。假基因的发现假基因最初是Jacq等1977年在非洲爪蛙 In recent years, in some eukaryotic gene structure research, a DNA sequence closely related to a functional gene has been found, which has obvious homology with its corresponding functional gene in nucleotide sequence, A variety of mutations that make it inoperable, such a DNA sequence is called “pseudogene” (Pseudogene). The discovery of pseudogenes The pseudogenes were originally from Jacq et al., 1977 in African clawed frogs
