DNA连接酶也称DNA黏合酶,在分子生物学中扮演一个既特殊又关键的角色,那就是把两条DNA黏合成一条。无论是双股或是单股DNA的黏合,DNA黏合酶都可以借由形成磷酸酯键将DNA在3'端的尾端与5'端的前端连在一起。 rna聚合酶的作用部位是什么 王嫘副主任医师 中国医科大学附属第一医院 三甲| 专科第3 ...

Vitamin C increases viral mimicry induced by 5-aza-2'-deoxycytidine Vitamin C deficiency is found in patients with cancer and might complicate various therapy paradigms. Here we show how this deficiency may influence the us... M Liu,H Ohtani,W Zhou,... - 《Proc Natl Acad Sci U S A》 ...
2b). The plasmid was separated into 3, 4, 5 or 6 fragments using PCR, and these fragments were treated with DpnI to remove the circular template. The control samples were prepared by using a similar amount of input DNA without supplementation with the XthA enzyme. The negative colonies ...
An algorithm to simulate DNA sequence evolution under a general stochastic model, including as particular cases all the previously used schemes of nucleotide substitution, is described. The stimulation is carried out on finite, variable length, DNA sequences through a strict stochastic process, accordin...

5). These variations also qualitatively agree with intensity variaitons in the single molecules studies in Fig. 3. This might reflect the presence of two origins of replication that are present in P1-like plasmids, oriR and oriL. GC-skew also helps predicting the location of the leading ...
DNAs of group B Ads (Ad3, 7, 11, 14, 16, and 21) hybridized 89 to 94% (HAP; 81 to 89% by S1 nuclease) with each other and 9 to 20% (HAP; 8 to 15% by S1 nuclease) with DNAs of other types. DNAs of group C Ads (Ad1, 2, 5, and 6) hybridized 99 to 100% with...
