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...

The other type of nucleic acid, RNA, is mostly involved in protein synthesis. The DNA molecules never leave the nucleus but instead use an intermediary to communicate with the rest of the cell. This intermediary is the messenger RNA (mRNA). Other types of RNA—like rRNA, tRNA, and micro...

A process for distinguishing nucleic acid segments on the basis of nucleotide differences, thereby providing a rapid, convenient means for detecting mutation, is disclosed. The present process comprises synthesizing separately complementary nucleic acid strands on each of at least two target nucleic acid...

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...
Nucleic acid detection is a key technique that enables the detection of specific nucleotide sequences and ultimately unveils the presence of a pathogen or early onset of a diseased state. From: Progress in Molecular Biology and Translational Science, 2021 ...
