donor dna 中文意思是什麼
donor dna
解釋
供體-
A. thalianas were respectively introduced by ion beam with a collection of donor dna having a gradient genetic relation with a. thaliana. in vegetative phase of tl, the ratio of phenotypic variation showed no distinct difference among these transformed populations
用離子束介導與擬南芥菜親緣關系從近到遠一系列的外源供體的全dna轉化擬南芥菜，在轉化當代營養生長期，各轉化群體的表型變異情況沒有明顯的差別。 -
To some degree, the inheritance and segregation of variant traits had a link with genetic relation between exogenous dna donor and receipt
轉化當代和後代產生了許多變異個體，變異性狀的遺傳與轉化當代外源dna供體的親緣關系有一定的相關性。 -
Cc was cloned from a cell taken from near the ovary of a tortoiseshell cat, but she is not a carbon copy of her dna donor
茜茜是由一隻花貓卵巢旁的細胞克隆而來，但是她和她的"母體"並非長得一模一樣，她們的皮毛花紋還是有所不同的。 -
Using such an early donor cell might avoid the risk of accumulated dna damage
使用這樣的一個早期供體細胞可能避免積聚dna損傷的風險。 -
I ) two mutants ( hpab - 38 and hpab - 34 ) were designed based on the three - dimension structure of hpab - constructed by protein homology modeling method, ii ) the mutant molecules were generated by pcr and inserted into pfast hta donor plasmid, the later was then transformed into escherichia coli dhlobac to generate recombinant baculoviruses dna by site - specific transposition of an expression cassette into a baculovirus shuttle vector ( bacmid ) propagated in e. coli. the recombinant bacmids were isolated and transfected into insect sf - 9 cells to reproduce baculoviruses
4 . h隊b一p及其突變體高效表達工程菌的構建:將用pcr擴增的h隊b一p 、 h獄b一p35 、 h隊b一p34基因，分別與pinpointxa一3質粒連接，轉化jm109大腸埃希菌，獲得的工程菌在表達融合蛋白時不穩定，第5代后即見不到表達條帶。 -
In ion beam - mediated total dna transformation, the total dna consisted of all of genetic information in donor, and had multilateral effects on recipient, so there was no common rate of transformation to measure its effect, which meant that it was very difficult to decide an optimum condition of transformation such as influence. implantation experiments showed that the relation between the influence and survival of a. thailand was a saddle curve
在離子束介導外源全dna轉化中，外源全dna包含有供體的所有遺傳信息，這些外源片段對受體的影響是多方面的，因此轉化效果無法用統一的轉化率來衡量，這就給最佳轉化條件（主要是轉化劑量）的選擇帶來了很大的困難。
