Because the genetic code is redundant for most amino acids, different codons can be used in a given position without altering the structure of the protein for which the gene codes. This flexibility permits information encoding structural, and therefore functional, properties of RNA and DNA to be transmitted simultaneously by a protein-coding sequence of DNA. Among the other messages that might be transmitted, it is proposed, is one modulating the evolution of the DNA itself.
由于大多数氨基酸的遗传密码是冗余的,因此在给定位置可以使用不同的密码子,而不会改变该基因所编码蛋白质的结构。这种灵活性使得编码RNA和DNA的结构(进而功能)特性的信息能够由DNA的蛋白质编码序列同时传递。有人提出,在可能传递的其他信息中,有一种信息可以调节DNA自身的进化。
