顾名思义，5种碱基中，腺嘌呤和鸟嘌呤属于嘌呤族（缩写作R），它们具有双环结构。胞嘧啶、尿嘧啶、胸腺嘧啶属于嘧啶族（Y），它们的环系是一个六元杂环。RNA中，尿嘧啶取代了胸腺嘧啶的位置，值得注意的是，胸腺嘧啶比尿嘧啶多一个5位甲基，这个甲基增大了遗传的准确性。碱基通过共价键与核糖或脱氧核糖的1位碳原子相连而形成的化合物叫核苷。核苷再与磷酸结合就形成核苷酸，磷酸基接在五碳糖的5位碳原子上。DNA(脱氧核糖核酸)的结构出奇的简单。DNA分子由两条很长的糖链结构构成骨架，通过碱基对结合在一起，就象梯子一样。整个分子环绕自身中轴形成一个双螺旋。两条链的空间是一定的，为2nm。在形成稳定螺旋结构的碱基对中共有4种不同碱基。根据它们英文名称的首字母分别称之为A(ADENINE 腺嘌呤)、T(THYMINE 胸腺嘧啶)、C(CYTOSINE 胞嘧啶)、G(GUANINE 鸟嘌呤)，另有U（URACIL尿嘧啶）。DNA与RNA共有的碱基是腺嘌呤、胞嘧啶和鸟嘌呤。胸腺嘧啶存在于DNA中，而尿嘧啶则存在于RNA中。每种碱基分别与另一种碱基的化学性质完全互补，嘌呤是双环，嘧啶是单环，两个嘧啶之间空间太大，而嘌呤之间空间不够。这样A总与T配对，G总与C配对。这四种化学“字母”沿DNA骨架排列。“字母”(碱基)的一种独特顺序就构成一个“词”(基因)。每个基因有几百甚至几万个碱基对。嘌呤和嘧啶都有酮-烯醇式互变异构现象，一般生理pH条件下呈酮式。 AGCT（U）四种碱基在DNA中的排列遵循碱基互补配对原则有些核酸中含有修饰碱基（或稀有碱基），这些碱基大多是在上述嘌呤或嘧啶碱的不同部位甲基化（methylation）或进行其它的化学修饰而形成的衍生物。例如有些DNA分子中含有5-甲基胞嘧啶（m5C），5-羟甲基胞嘧啶（hm5C）。某些RNA分子中含有1-甲基腺嘌呤（m1A）、2，2-二甲基鸟嘌呤（m22G）和5，6-二氢尿嘧啶（DHU）等。
As the name implies, adenine and guanine belong to the purine family (abbreviated as R) in five kinds of bases, and they have a bicyclic structure. Cytosine, uracil, thymine belongs to pyrimidine family (Y), their ring system is a six-membered heterocyclic ring. In uracils, uracil replaced the thymine position, notably, thymine is more a methyl 5-position than uracil, which increases the genetic accuracy. The base is formed by the covalent bond with the 1-carbon atom of ribose or deoxyribose to form a nucleoside. The nucleoside then binds to the phosphate to form a nucleotide which is attached to the 5 carbon atom of the pentasaccharide. The structure of DNA (DNA) is surprisingly simple. A DNA molecule consists of two long chains of sugar chains, joined together by base pairs, like a ladder. The entire molecule forms a double helix around its own axis. The space between the two chains is fixed at 2 nm. There are 4 different bases in the base pair forming a stable helical structure. The first letters of their English names are called A (ADENINE adenine), T (THYMINE thymine), C (CYTOSINE cytosine), G (GUANINE guanine) and U (URACIL uracil). The common bases for DNA and RNA are adenine, cytosine and guanine. Thymine is found in DNA, while uracil is found in RNA. Each of the bases is compley complementary to the chemical properties of the other base, respectively. The purine is bicyclic, the pyrimidine is monocyclic, the space between the two pyrimidines is too large, and the space between the purines is not enough. Thus A always paired with T and G always paired with C. These four chemical "letters" are arranged along the DNA backbone. A unique order of "letters" (bases) constitutes a "word" (gene). Each gene has hundreds or even tens of thousands of base pairs. Both purine and pyrimidine have keto-enol tautomerism and are generally keto at physiological pH. AGCT (U) four bases in the DNA in accordance with the principle of complementary base pairing Some nucleic acids contain modified bases (or rare bases), these bases are mostly in the above purine or pyrimidine base methylation Methylation or other chemical modification. For example, some DNA molecules contain 5-methylcytosine (m5C), 5-hydroxymethyl cytosine (hm5C). Some RNA molecules contain 1-methyladenine (m1A), 2,2-dimethylguanine (m22G) and 5,6-dihydrouracil (DHU) and so on.
