ts gene 中文意思是什麼
-
The average transition : transversion ratio was 1. 0 which indicated the genetic differentiation was great. the ration was 2 in nuclear dna gene. as a rule the ts : tv ratio decreased with the increasing genetic distance
1數據分析軟體，構建蚜總科蚜蟲分子系統樹，探討這些類群這間的分類地位和親緣關系，這在國內外尚屬首次。 -
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， 。 -
That is to add a special fluorescence - based dna internal standard in the telomerase elongated ts primers, then do pcr amplification after a step of refinement ( hydroxybenzene / chloroform extracting, and deposited by ethanol ). sequencing analysis of pcr product was done on 310 gene scan analysis ?. 1. 2 dna sequencer to determine telomerase activity. notably, this method eliminated the restraining factors of taq dna polymerase, making it possible to erase the sample differences met in pcr and eradicate the annoying phenomena of pseudo negative results
在kim等開發的端粒重復擴增分析法（ trap ）的基礎上進行改進，即通過對端粒酶延伸ts寡核昔酸反應產物的精製，消除了pcr擴增中抑制taq酶活性的因素，從而減少了樣品之間pcr擴增上的差異和假陰性現象的發生，提高了判斷樣品端粒酶陰、陽性的準確率和定量的準確性。
