组成核酸的基本单位是核苷酸,脱氧核糖核酸就是DNA，核糖核酸就是RNA，他们的基本单位分别是脱氧核苷酸，核糖核苷酸．书上说的：核苷酸组成DNA 是笼统的说法 应该是:脱氧核苷酸是组成DNA的成分之1 另外一分子DNA是由1分子磷酸，1分子脱氧核糖，1分子含氮碱基组成的 而RNA是核糖 所以应该是脱氧核苷酸是组成D...

Before embarking on a description of nucleotide and nucleic acid structures, let us examine the biological importance of this class of molecules and find out why their structural principles should be known at the atomic level.doi:10.1007/978-1-4612-5190-3_1Wolfram Saenger...

Biochemists call it the central dogma: Genetic material, in the form of a long nucleic acid polymer called DNA, stores a digital record of every protein's design.(生物化学家将这套系统称之为中心法则(centraldogma):以长链核酸聚合物形式存在的DNA是遗传物质,它储存着每种蛋白质设计的数据记录。) ...
The meaning of NUCLEIC ACID is any of various complex organic acids (such as DNA or RNA) that are composed of nucleotide chains.
《Nucleosides Nucleotides & Nucleic Acids》(《核苷 核苷酸和核酸》)是一本由Taylor and Francis Ltd.出版的生物-生化与分子生物学学术刊物,主要刊载生物-生化与分子生物学相关领域研究成果与实践,旨在打造一种学术水平高、可读性强、具有全球影响力的学术期刊。本刊已入选SCIE来源期刊。该刊创刊于2000年,出版周期Mont...
So now we know what makes up nucleosides, but we’re still short of having our nucleic acid. Next comes the phosphate group. When the sugar of a nucleoside is linked to one or more phosphate groups, you get a nucleotide. These are connected by an ester linkage — oxygen covalently bound...
