crossing sequence
解釋
交叉序列-
In the experiment, the full code sequence of bar gene was cloned by pcr from transgenic herbicide resistant bobwhite wheat and checked. it was expressed in e. coli and its protein was determined. after having been properly modified, the bar gene which correctly codes pat was cloned into binary vector pbi121 and then transferred into lba4404 by triparantal crossing, which is the prerequisite work for genetic transformation
本實驗從抗除草劑轉基因bobwhite小麥中，利用pcr克隆的方法擴增出bar基因全長，並在原核表達系統中表達，鑒定表達蛋白的活性，將能夠正確編碼ppt乙酰轉移酶的bar基因片段，經過適當的修飾構建入真核表達載體。 -
The modified sequence was cloned into binary vector pbi121. the constructed expression vector was named pbi121 - bar, then transferred into agrobacterium tumefaciens lba4404 by triparental crossing. thus the project bacterium has been successfully constructed
改造后的目的基因克隆于真核表達載體pbi121 ，構建表達載體pbi121 - bar ，通過三親雜交法將真核表達載體pbi121 - bar轉入農桿菌lba4404 ，成功構建出工程菌。 -
As a special type of multigene family, rdna undergo concerted evolution by homogenizing forces through processes such as gene conversion, unequal crossing - over. for a long time we assumed strong concerted evolution in rdnas of various animal and plant species and direct pcr - sequence approach has been widely used in molecular systematic research
作為特殊的多基因家族成員， rdna會受均一化力（ homogenizingforces ）的作用，通過基因轉換、不等交換等機制，形成基因的致同進化（ concertedevolution ） 。 -
Meanwhile, two private cars were travelling along the fast lane of san tin highway in the same direction in sequence. the man who was crossing the road was then reportedly knocked down by the first private car
此時，兩輛私家車正沿新田公路快線往同一方向一前一後行駛，第一輛私家車據報撞向該名男子。
