The examples so far have naively assumed that the penalty for a mismatch between DNA bases should be equal — for example, that a G is as likely to mutate into an A as a C.
目前为止的示例都假定DNA碱基对之间不匹配的扣分应该相等 —例如，认为G 变异为A与变异为 C 的可能性相当。
For DNA, these units are the c, t, a and G bases, and for proteins the units are 20 different amino acids.

形成DNA、RNA单体以及编码遗传信息的化学结构，也就是组成碱基对的碱基包括A、G、T、C、U。
Human DNA has only 4 basic building blocks (commonly written as g, a, t, and c), so this is not a far-fetched theory.
人类DNA只有4种基本组成部分(通常写作g、A、t和c)，因此这不是一种牵强附会的理论。
Thus on top of the dependence on g-c content, the stability of pna-dna duplexes also depends on the purine fraction of the PNA strand.
因此，肽核酸- DNA二聚体的稳定性除了依赖g - C配对的含量外，还与肽核酸链上的嘌呤含量有关。
In addition to the familiar duplex DNA, certain G-rich DNA sequences can fold into a variety of four-stranded structures, which are called G-quadruplexes.
富含鸟嘌呤碱基的DNA序列能够通过鸟嘌呤环的互联作用形成四链螺旋结构，这种结构被称为G-四链体。

方法获取10例淋巴瘤患者的活检淋巴结组织，以CGH技术检测淋巴瘤基因组d NA拷贝数的变化。
The examples so far have naively assumed that the penalty for a mismatch between DNA bases should be equal - for example, that a G is as likely to mutate into an a as a c.
目前为止的示例都假定DNA碱基对之间不匹配的扣分应该相等-例如，认为G变异为A与变异为C的可能性相当。
According to different chromosomes, a region of DNA, e. g., quantitative trait locus (QTL) can be found that is related to a particular phenotypic trait.
根据不同的染色体区域的DNA，例如，数量性状位点(QTL)可以发现，涉及到某一特定表型性状。
Literature search indicates that there is no published investigation on the stability or variation of DNA methylation associated with in vitro propagation of g.
