Results: Enzyme digestion and sequence determination and analysis confirmed that the Construction of recombinant plasmid was correct.

结果：酶切鉴定及核苷酸序列测定表明重组质粒的构建完全正确。

Two couples of primers were synthesized according to the sequence of the pelA gene. They are used to prove that the pelA gene obtained from NTT33 by PCR.

根据核苷酸序列分析结果设计引物，通过PCR的方法，在嗜碱芽孢杆菌NTT33的总DNA和p1350中分别扩增到预计大小的片段，证明pl350中的外源DNA片段来自於嗜碱芽孢杆菌NTT33。

To investigate the relationship between the angiotensinconverting enzyme insertion/deletion mutation and the aldosterone synthase (CYP11B2) gene C(-344)T single nucleotide polymorphism in pedigreed primary hypertension and pedigreed nomortension.

We also observed that the genomic regions with higher GC content tend to form nucleosome with greater stability.

我们在线虫核小体DNA中观察到的175-nt周期信号与在阴道滴虫基因序列中观察到的120.9-nt周期信号为同一类信号，反应的都是缠绕在核小体上的DNA与位于核小体之间的DNA在核苷酸组成上的不同。

A major clinical limitation of conventional antisense oligonucleotides is that they are rapidly degraded by nucleases.

一个主要的临床限制常规反核苷酸是，他们正在迅速退化核酸。
