The genome of the mouse (Mus musculus) contains a family of repeated DNA sequences defined by a 1.3 kb EcoRI fragment. Restriction maps of ten cloned fragments from this family have been determined. The fragments were of seven different types, based on the patterns of digestion obtained with AvaII, HindIII, and TaqI restriction enzymes. These seven unique sets of sequences fell into two classes, as defined by the position of a single HindIII site. Portions of fragments from each of the two classes were sequenced. Although certain regions of the repeat were highly conserved between classes, there was more intraspecific sequence divergence among the sequenced regions than has been observed for the short interspersed Alu family of repeated sequences in mammals. Sequences of both HindIII classes were found to be present within the mouse X chromosome; we can conclude that both classes must also be present on other mouse chromosomes.
小鼠（小家鼠）的基因组包含一个由1.3 kb的EcoRI片段定义的重复DNA序列家族。已确定了该家族十个克隆片段的限制性图谱。根据用AvaII、HindIII和TaqI限制性内切酶获得的消化模式，这些片段有七种不同类型。这七组独特的序列分为两类，由单个HindIII位点的位置定义。对两类中的每一类的片段部分进行了测序。尽管两类之间重复序列的某些区域高度保守，但测序区域内的种内序列差异比在哺乳动物中短散在Alu重复序列家族中观察到的要多。发现HindIII两类的序列都存在于小鼠X染色体中；我们可以得出结论，两类也必定存在于其他小鼠染色体上。
