您要查找的是不是：
- desired gene fixation 所要求基因固定
- Desired gene is placed between P-element ends,usually within a plasmid,and injected into preblastoderm embryos in the presence of transposase. 目的基因置于质粒内P因子中可在转座酶的作用下插入前胚盘胚。
- Aegilops species with D genome are the secondary gene pool of hexaploid common wheat for exploiting desired genes of wild species and enhancing the genetic diversity of commercial wheat varieties. 具有D染色体组的山羊草属种是六倍体普通小麦的二级基因源,蕴藏着丰富的抗性基因和遗传变异丰富,可供现代小麦改良利用。
- Consequently the desirable gene may be linked to a marker gene, e.g. a gene conferring resistance to an antibiotic in the growth medium. 如决定一种是否对培养基上抗菌素产生抗性的性状基因，就可作为标记基因用来判断外源基因是否转入。

- However, this failed to produce the desired result. 但这并没有产生预期的效果。

- Amber satin and white lace were exactly what she desired. 琥珀色的缎子和白色的饰带正是她所想要的。
- The position that a given gene occupies on a chromosome. 基因座在一条染色体上某种给定基因所占的位置
- Adjust the strap length as desired. 调整背带到所需长度。
- Half of the people who inherit the gene express it. 半数有这种遗传基因的人，皆显示出其影响
- He preset the video recorder at the desired time. 他按要求的时间预先把录像机调好。
