n.同源異型框

The islet-1 gene is a member of the LIM homeobox gene family. 新近研究表明，我們所關(guān)注的islet-1基因既是LIM同源框基因家族的一員。

Quox-1 gene is an Antp type homeobox gene isolated from the quail. Quox-1基因是從鵪鶉中分離得到的Antp 類型的一個同源異形盒基因。

Each of the genes contains a homeobox, a remarkably conserved DNA sequence. 每個基因含有一個同源異型盒，這是一個非常保守的DNA序列。

Homeobox genes play fundamental roles in the development of nervous system. 同源框基因在神經(jīng)系統(tǒng)乃至個體的發(fā)育過程中扮演著十分重要的角色。

Physical development occurs when a limb of the animal embryo stage, the homeobox gene. 肢體發(fā)育發(fā)生于有肢動物的胚胎階段，受同源異型基因控制。
