After a set of experiments , this paper describes the exist of introns in the individuals of genetic programming , which are redundant and give impact for evolution both positively and negatively 摘要通过众多的试验和分析，证实遗传规划的个体中存在基因内区，它对进化的收敛既有积极作用也有消极作用。
Asqs is 70 % , 77 % , 44 % and 39 % identical to squalene synthases from arabidopsis thaliana , tobacco , human and yeast , respectively . the asqs genomic dna has a complex organization containing 14 exons and 13 introns 青蒿鲨烯合酶氨基酸序列与拟南芥、烟草、人类、酵母鲨烯合酶的一致性分别为70 、 77 、 44 、 39 。
Its at content is 51 . 61 % . the whole gene consists of five exons and four introns . the mean at values for all the exons and all the introns are 49 . 35 % and 62 . 23 % respectively 野桑蚕-淀粉酶基因全序列的at为51 . 61 ，包含5个外显子和4个内含子，外显子的at平均值为49 . 35 ，内含子的at平均值为63 . 23 。
Better yet , it only goes into a few specific places in the genome - - and these are not obviously as safe as the aav site , because they tend to be in the gaps in the middle of genes called introns 尤其可贵的是，它只进入基因组的少数特异位置?这些明显地不如aav位点那么安全，因为它们倾向于进入称为内含子的基因中间缝隙。
