Among these TFBSs, the FORKHEAD transcription factor family is somewhat resistance to the rSNP alterations.

其中，FORKHEAD家族中的转录因子，相较於其它转录因子，特别不易受到单核苷酸变异的影响。

By fluorescence in situ hybridization. Strong fluorescence signals with the probes were observed in 20%~60% formamide concentrations.

的16S rRNA基因序列，设计荧光原位杂交检测博德特氏菌的寡核苷酸探针FW_iso_62和FW_iso_761，在20%~60%甲酰胺均有很强的荧光信号。

Antifolate Alimta derived from pyrrolo[2,3-d]pyrimidine is a multitargeted antitumor agent, it can inhibit at least five major folate-dependent enzymes: thymidylate synthase, dihydrofolate reductase, glycinamide ribonucleo -tide formyltransferase, aminoimidazole ribonucleotide formyl transferase and C-1 tetrahydrofolate synthetase(C1-S).

吡咯并[2，3-d]嘧啶类叶酸拮抗剂Alimta是一种多靶向的抗癌药物，它能抑制至少五种叶酸依赖性酶：胸苷合成酶、二氢叶酸还原酶、叶酰多聚谷氨酸合成酶、甘氨酰胺核糖核苷酸转甲酰酶及C1-四氢叶酸合成酶(C1-S)。。

Four groups of oligonucleotides were successively cloned in pMD18-T vector to obtain four large fragments. Ligation of these four fragments resulted in a cloned DNA MgE717 coding for the 29～268 amino acid region of gE. Sequencing result showed that there is a mutation at 255 amino acid, Asn instead of Asp.

分四段分别合成，基因拼接得到了改造后的基因片段MgE717，经测序，除了在gE基因+763位核苷酸处存在一碱基置换，导致第255位的氨基酸残基由Asp突变为Asn，其余的序列与PrV鄂A株gE基因的氨基酸序列相符。

For constructing strong combined promoter to enhance the foreign gene expression in Fowlpox virus vector, four oligonucleotides were synthesized according to the essential structure of the vaccinia virus nature promoter P7.5 and were used for generating early and late promoters.

要提高外源基因在鸡痘病毒载体的表达量，必须使用强启动子来控制表达。为构建较强的启动子组合，根据痘苗病毒天然启动子P7.5的结构，人工合成4条寡核苷酸，形成一个早期启动子和一个晚期启动子，其首尾可相互连接。

Ribonucleic acid and 5'-nucleotide were tested for fructification of Tricholoma matsutake in the field.

摘 要：施用核糖核酸和5'-核苷酸试验，其对生长于林间的松茸子实体的活化作用。

SUMMARY: We have developed a program SOAP for efficient gapped and ungapped alignment of short oligonucleotides onto reference sequences.

概要：我们开发了一个高效的带有gap和没有gap的比对短寡核苷酸到参考序列上的程序-SOAP。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
