sry 中文意思是什麼
sry
解釋
sry基因-
Using a pair of degenerate primers based on the conservative region, hmg - box, of human sry gene, tow different fragments of sox gene, essox3 and essox22 were amplified from female and male eriocheir sinensis, the sequence results indicated that essox3 and essox22 shown high homology to human sox genes, and the identities to human sox genes in dna sequence and amino acid sequence are 84 % 、 85 % and 97 % 、 81 %, respectively. it might be concluded that sox gene was highly conservative in phylogenesis
二、研究論文1 、參照人sry基因hmg - box保守區的序列，設計一對兼并引物， pcr擴增了中華絨螯蟹的sox基因，並對擴增產物進行了克隆和測序。結果在雌雄個體中篩選出兩個不同的sox基因essox3和essox22 ，其dna序列和編碼的氨基酸序列與人相應sox基因的相似性分別為84 % 、 85 %和97 % 、 81 % ，顯示該基因在進化上具高度的保守性。 -
Using the hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which sry transcription can be detected failed to yield any positive results of xist. female embryos at the pronucleus stage and 2 - cell failed to produce any positive result of sry and xist too. while since the 4 - cells period, xist is constantly transcribed until blastocyst stages
然後利用實驗一確定的pcr條件，以hprt為陽性對照，用巢式rt - pcr對小鼠早期胚胎進行xist基因的轉錄分析，結果發現，轉錄sry基因的睪丸組織以及雄性胚胎，從受精卵發育到囊胚的過程中，基本上不轉錄xist基因；不轉錄sry基因的雌性卵母細胞和雌性胚胎，從出現原核開始，到發育至2 -細胞期的過程中， xist基因一直不轉錄，但是，從4 -細胞期開始，一直到孵化前囊胚階段，雌性胚胎都轉錄xist基因。 -
Part two : studies l. the sox gene of rana rugulosa wiegmann was amplified by using the technique of pcr with a pair of primers which specially amplify the conserved motif ( hmg - box ) of human sry gene
二、研究報告1 、採用pcr技術，以特異擴增人sry基因hmg - box保守區的一對特異引物擴增了虎紋蛙sox基因，優化了擴增條件。 -
2. using a pair of degenerate primers based on the conserved region, hmg - box, of human sry gene, eight different fragments were amplified from both female and male rana rugulosa wiegmann then cloned by using pmd18 - t vector and sequenced
2 、參照人sox基因設計了一對兼并引物，擴增了虎紋蛙的sox基因，並對擴增產物進行了克隆和測序。 -
All male goat - rabbit interspecies clone embryos samples had bands representing sry - specific, while female goat - rabbit interspecies clone embryos and control samples had no band
所有雄性樣品中均出現清晰可見的特異dna擴增帶，而雌性樣品和空白對照中無擴增片段出現。 -
Quantitative study of cell - free fetal dna - sry gene in preterm labour maternal plasma
血糖調節受損者糖化白蛋白與心血管危險因子的相關性 -
Part two : studies ; l. the sox gene of dinodon refozonatum was amplified by using a pair of primers which can amplify the conservative motif ( hmg - box ) of human sry gene. the amplification band was observed in both male and female dinodon refozonatum, whose length was consistent with that of human sry gene, which about 220bp. the result of sscp analysis showed that there were many differences in the sox gene sequence between dinodon refozonatum and human, and there was a few differences between male and female dinodon refozonatum. 2. using a pair of degenerate primers based on the conservative region, hmg - box, of human sry gene, six different fragments were amplified from either female or male dinodon refozonatum, then cloned by using pmd18 - t vector and sequenced
結果顯示： （ 1 ）赤鏈蛇基因的擴增片段與人sry基因擴增片斷大小相同，為220bp左右； （ 2 ）雌、雄赤鏈蛇sox基因的擴增片段大小雖然與人的相同，但其單鏈遷移率與人的有較大差異，而且雌雄個體間有明顯差異，預示該基因的dna序列在雌雄個體中可能有差異； 2 、參照人sry基因hmg - box保守區的序列，又設計一對兼并引物，擴增了赤鏈蛇的sox基因，並對擴增產物進行了克隆和測序。 -
The unexpected sequence change in ts - 41, - 42 and, as - 41, - 42 may have occurred after divergence of amniotes. it is the first report that the sequence homologues of the progenitor of the mammalian testis - determining gene sry were identified in reptile. these findings might provide molecular evidences that sry - related genes may be involved into tsd
進一步序列分析表明： as41 42 、 ts41 42與非爬行類脊椎動物的sox - 1 、 - 2 、 - 3的氨基酸同源性低於非爬行類脊椎動物包括哺乳類、鳥類、兩棲類和魚類的腸工一1 、一2 、一3相互之間的氨基酸同源性， 。 -
We employed the rt - pcr method to investigate whether xist is transcribed in some of the developing stages of mouse. first, different mouse tissues which have been proved to transcribe xist and sry simultaneously were used to establish the appropriate conditions for xist and sry rt - pcr
首先提取了6周齡昆明白小鼠幾個組織的rna ，用普通反轉錄法擴增xist和sry以確定rt - pcr的條件， sry的主要作用是用來做性別鑒定。
