  • Nucleotide - Wikipedia
    Nucleotide (abbreviated "nt") is a common unit of length for single-stranded nucleic acids, similar to how base pair is a unit of length for double-stranded nucleic acids
  • Nucleotide | Description, Types, Function, Facts | Britannica
    A nucleotide is any member of a class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group
  • Nucleotide Definition, Structure, and Function
    A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) These molecules consist of three primary components: a nitrogenous base, a sugar molecule, and one or more phosphate groups
  • 核苷酸_百度百科
    核苷酸(nucleotide)是一类由嘌呤碱或嘧啶碱、核糖或脱氧核糖以及磷酸三种物质组成的化合物,又称核甙酸。 戊糖与有机碱合成核苷,核苷与磷酸合成核苷酸,8种核苷酸组成核酸。
  • 核苷酸 - 维基百科,自由的百科全书
    核苷酸 (英語: nucleotide)为一种 核苷磷酸 (nucleoside phosphate) [1][2],是 核苷 中 戊糖 分子的碳原子上的羟基与一分子磷酸缩合脱水形成的 磷酸酯 [3],若无特别指明,一般指 5′-核苷酸。 核苷酸是 核酸 的基本组成单位,化学结构属于一种 磷酸酯。
  • Nucleotide - National Human Genome Research Institute
    A nucleotide is the basic building block of nucleic acids (RNA and DNA) A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base

  • 核酸与核苷酸(二) - 知乎
    核苷中戊糖的羟基被磷酸酯化,就形成核苷酸(nucleotide)。 核糖核苷的糖环上有三个羟基,可形成三种核苷酸:2’、3’和5’-核糖核苷酸。 脱氧核糖只有3’和5’两种。 生物体内游离存在的多是5’核苷酸。 用碱水解RNA可得到2’和3’核糖核苷酸的混合物。
