您要查找的是不是：
- They were the variation between individuals and populations because of single nucleotide base alteration, including transition, transversion, insertion and deletion. 它是由单个碱基的转换、颠换、插入或缺失引起的点突变，使得群体之间和个体之间产生了差异。
- A set of three nucleotide bases on an mRNA molecule is called a codon. 翻译是在细胞质中进行的。它是指以信使RNA为模板，合成具有一定氨基酸顺序的蛋白质的过程。）
- SNPs consist of a single nucleotide base alteration including transition and transversion.They are stable and reliable mutation and are frequently referred to as bi-allelic makers. 它是由单个碱基的转换或颠换引起的点突变，稳定而可靠，并通常以二等位基因的形式出现。
- Chemical alterations of nucleotide bases are often removed by BER, as in G1 phase. 碱基的化学修饰通常在G1阶段由BER去除。
- The information inside a DNA molecule is encoded by the nucleotide bases adenine, thymine, guanine and cytosine (A, T, G and C). DNA分子携带的资讯是由核苷酸碱基腺嘌呤（A）、胸腺嘧啶（T）、鸟嘌呤（G）及胞嘧啶（C）所编写。
- Degenerate code A part of the genetic code in which some amino acids are coded for by more than one triplet of nucleotide bases (codons). 简并密码子：大多数氨基酸都可以具有好几组密码子。
- Abnormal nucleotide base sequence 异常核苷酸碱基序列
- Instead the rRNA immediately crumples itself into a defined shape, within which certain nucleotide bases bind to one another, much like a terminator hairpin. rRNA一旦合成后，会折叠成特定的形状，其中某些核苷酸碱基彼此会立刻配对，形成有点像前面提到终止转录的发夹形构造。
