本研究在对我国野生玫瑰种质资源进行全面调查的基础上，从形态学、生理学、植物化学、孢粉学及分子生物学5个层面，系统地研究了我国野生玫瑰当前的资源状况，弄清了野生玫瑰基本的生物学特性及其变异，并利用AFLP分子标记技术对部分玫瑰野生种质资源和品种资源的遗传多样性和亲缘关系进行了分析。

The job of pantothenate kinase is to grab a molecule of pantothenic acid (vitamin B-5) and another molecule that contains a chemical group called "phosphate."

泛酸激酶的工作就是捕获名为泛酸的分子（维生素B5）和另一种含有磷酸化学基团的分子。

Then they used the pattern formed by the beams as they bounced off the crystals to create computer-generated, 3-D images of the patterns of twisting and folding amino acid chains that make up the different types of pantothenate kinase and their interactions with the other molecules.

然后从晶体的反射光形成的图像出发，通过电脑生成组成不同类型泛酸激酶的折叠扭曲的氨基酸分子链的三维图像以及它们与其他分子相互作用时形成的三维图像。

With the progress of molecular biology and the recognition of molecular pathology, the studies of s...

随着分子生物学技术的发展和对疾病分子病理学认识的深入，使得某些难治性疾病的研究进入了基因治疗的时代。

By employing two kinds of molecular marker of mitochondrial DNA, i. e. Cyt b and CoI gene, the sequences of 15 species representing 6 families from Passeriformes were compared. We analysed their sequences compose and characteristic with the sorft of MEG3.1, and built the phylogenetic trees in PAUP~*4.0. We deeply analysed the feasibility that CoI gene qua the marker to research the phylogenetic relationship of Passeriformes, and afford the academic proof for building the DNA barcoding of the birds.
