The main theories which have been suggested to explain the origin of genetic code organization are discussed. The coevolution theory, which considers the genetic code as a map of the biosynthetic relationships between amino acids, seems to be based on a mechanism that links it closely to certain stages of the origin of metabolism, which makes it preferable to other theories proposed as explanations of genetic code origin. Relationships, incompatibilities and compromises between the various theories are highlighted and these seem to indicate a certain lack of clarity in this field of research.
本文讨论了为解释遗传密码组织起源而提出的主要理论。共进化理论将遗传密码视为氨基酸之间生物合成关系的图谱,该理论似乎基于一种将其与代谢起源的某些阶段紧密联系起来的机制,这使得它比其他作为遗传密码起源解释而提出的理论更具优势。文中强调了各种理论之间的关系、不相容性和折衷之处,这些似乎表明该研究领域存在一定的模糊性。
