transgenic animals 中文意思是什麼
-
The transgenic plants have been studying for more than ten years, which have some advantages including that the plants are autotrophy not requiring expensive media or strict culture conditions, and the plant viruses cannot infect human, compared with other systems such as microbe fermentation and transgenic animals
與微生物發酵、動物細胞和轉基因動物等生產系統相比，轉基因植物不需要昂貴的設備和嚴格的培養條件，具有光合自養、成本較低，植物病毒不感染人類等優點，已成為一類比較廉價和安全的生物反應器。 -
Different amount of copies in different tissues attribute to the different density of positive signals. the result of the experiment suggested that the transgenic animals can be produced by spermatozoa - mediated gene transfer after the entrapment of liposome. and because the exogenous dna occurs losing the segments. partly integration, or existin g outside of genome dna, the rate of chimerism is relatively high
結果表明： （ 1 ）脂質體包裹外源基因轉染精子的方法，可將外源基因導入受精卵中，能夠獲得轉基因動物，並得到了較高的轉基因陽性率； （ 2 ）精子攜帶的外源dna的整合過程是隨機的，在受精過程和胚胎早期分化過程中可能發生了片段丟失、不完全整合或游離于基因組存在而產生嵌合體。 -
The technique of microinjection is significant to embryo ' s development. for example, the different volume of microinjection will have direct effect on the in vitro survival rate of the embryos and even the successful rate of the transgenic animals
顯微注射技術對胚胎發育有著關鍵性的影響，如注射劑量的不同將直接影響到胚胎體外發育的存活率乃至影響整個轉基因動物的成功率。 -
With the help of es cells, scientists are trying to set up the cell and animal models of diseases such as diabetes, alzheimer ' s disease and parkinson ' s disease, produce the transgenic animals
研究者們試圖用es細胞建立糖尿病、老年型癡呆、帕金森氏癥等遺傳疾病轉基因動物模型。 -
A major problem in the production of transgenic animal mammary gland bioreactors is the low production rate of high - expressing transgenic animals due to the position effect to overcome that, including all regulatory elements in the constructs of expression vector seems to be the most reasonable way
動物乳腺生物反應器生產中存在的主要問題之一，就是由於位置效應的影響而難以獲得高效表達的轉基因動物。為了克服這個問題，在轉基因表達載體中引入了多種諸如mars和insulator等的調控元件。 -
By far, about 80 % or more transgenic animals are constructed through microinjection
目前80以上的轉基因動物模型都是利用顯微注射來構建完成的。 -
In order to supply the es cells needed for the research of transgenic animals in our labortaory in future, we did some work of isolating es cells from mouse
同時，為以後開展轉基因動物模型的研究，我們還進行了小鼠es細胞建系的部分工作。 -
With the appearing of transgenic animal, it is possible that people can rebuild the genome of animals by gene recombination and contrive research on relative gene ' s structure and function in viviperception. this is a multidimension system of gene research with regard to providing new approaches and thoughts from molecule to individual arrangement
轉基因動物的出現，使人類可以通過基因重組的各種方法人為的改造動物基因組，在動物活體水平上研究有關基因的結構和功能，是一個四維時空的研究體系，為從分子到個體的各個層次，多維的研究基因提供了新的方法和思路。 -
In order to do such research, we must have sufficient es cells ; especially for the production of transgenic animals, es cells within 10 passages are required. and if for the study of cell therapy, the problem of other differentiated cells coexisting in the wanted cells - derived from es cells must be resolved
進行一系列研究必須要有足夠的es細胞，特別是建立轉基因動物模型，需要10代以內的es細胞；而用作細胞治療研究也必須解決其他分化細胞的影響問題。 -
Several attempts have been made to utilize modern transgenic techniques to express afps genes in frost - susceptible animals and crops to increase their freezing tolerance, and it has been reported that some transgenic organisms do acquire increased cold - resistance. the giant freshwater pravm ( macrobrachium rosenbergii ) is of great economic value and cultured around the world. this prawn has been popular in chinese mainland due to its delicious taste and abundant nutrition since it was introduced here
羅氏沼蝦（ giantfreshwaterprawn ， macrobrachiumrosenbergii是一具高蛋白、低脂肪、在全球范圍內都有養殖記錄的重要水產品種，深受人們喜愛，但由於屬熱帶、亞熱帶種類，對低溫的適應能力較差，低於14就會死亡，最低要18才能生長，其不耐低溫的特性大大增加了其養殖成本，嚴重阻礙了羅氏沼蝦養殖業的發展。 -
In this paper, three human dna fragments were coinjected into mice in order to study the influence of uncoding large dna fragment on hsa or hfen1 gene ' s integration efficiency, to explore methods to produce high expression of human serum album animals, to find out how to establish multi - transgenic animals in a way of saving time and money, to provide experience and reference to others. it mainly contains the following aspects : firstly, according to the sequence of human serum album gene cdna in genebank, one primer was designed
本實驗以小鼠為研究對象，採用兩種基因? hsacdna 、 hfen1和一種非編碼大片段dna進行共注射，旨在探索非編碼大片段dna對hsa和hfen1基因整合的影響及建立提高hsa基因整合效率的轉基因動物的方法，同時，探索多基因轉基因動物建立的策略，以便尋求一種既節省時間，而又簡單經濟的轉基因方法，為以後的研究提供一點的探索性經驗和參考。
