在分子生物学方面，本论文采用RAMP技术，对猴头菌属菌株进行DNA提取、PCR扩增及图谱分析，发现各菌株在图谱上均有丰富的表达，并呈现很强的特异性，其差异程度也各不相同。

Five of fifty random primers amplified DNA polymorphism hands in RAPD analysis of seed-derived seedlings and of in vitro regenerated plantlets taken at random. One primer eyen amplified the difference between the regenerated plants. This suggested that there was some variation in DNA in plants of M. sativa regenerated in vitro.

随机选取实生苗和下胚轴愈伤组织再生苗进行RAPD分析，结果表明，所用的50个随机引物中有5个扩增出差异性条带，甚至再生植株之间也有1条引物扩增的条带有差异，这说明经组织培养所得到的再生植株与实生苗相比，在DNA水平上发生了一定程度变异，并且这种变异也存在于再生植株之间。

Denaturing high performance liquid chromatography and direct sequencing in conjunction with DNA pooling were used as possible strategies for augmenting the efficiency, economy, and throughput of SNPs detection in the finless porpoise.

Results After 50 mmol·L-1 Taurine was added to the spleen lymphocyte suspension containing 0.1 mmol·L-1 glycolaldehyde, the cellular DNA damage rates were markedly decreased (P.01) and the migration distances of DNA were significantly reduced (P.01) as compared with positive control group, and Taurine reduced the carbonyl compound contents in a reactive system in a dose-dependent manner.

结果：在0.1 mmol·L-1乙醇醛溶液中加入50 mmol·L-1牛磺酸后，小鼠脾淋巴细胞DNA的损伤率较阳性对照组明显降低（P.01），彗星实验的迁移距离也显著缩短（P.01），牛磺酸呈剂量依赖性明显降低反应体系中乙醇醛的含量。

It was this nuclear annihilation that spiraled all species including mankind from 5000 strands to 2 strands of DNA,and at 2 strands there is not enough knowledge to retain an inherent understanding of groundedness thereby causing humans to by in large feel "unsafe" and exist in fear.

因为这次核毁灭将所有物种包括人类，从5000股DNA降低到2股之中。2股DNA不再保有足够的知识来保持内在的根植理解，因此导致大部分人类感到&不安全&而生活在恐惧中。
