Bovine fetal and adult globin genes were cloned and subjected to DNA sequence analysis. Both of these genes contained insertions of Alu-type repetitive DNA within their introns. Comparison of cow and goat beta-type globin genes indicates that intragenic DNA insertions played a role in their evolution. These data support the theory that Alu-type repeats maintain genetic diversity by inhibiting gene conversion.
克隆了牛胎儿和成年期的珠蛋白基因,并对其进行了DNA序列分析。这两个基因在其内含子中都含有Alu型重复DNA的插入序列。牛和山羊β型珠蛋白基因的比较表明,基因内DNA插入在它们的进化中发挥了作用。这些数据支持了Alu型重复序列通过抑制基因转换来维持遗传多样性的理论。
