复制(replication) 是指遗传物质的传代,以母链DNA为模板合成子链DNA的过程

he third and final part of this book explores the bio￾chemical mechanisms underlying the apparently con￾tradictory requirements for both genetic continuity and the evolution of living organisms. What is the molecular nature of genetic material? How is genetic information transmitted from one generation

1氨基酸 (一)蛋白质水解最后成为氨基酸混合物 酸水解得19种L-AA,色氨酸破坏 碱水解得色氨酸,其余氨基酸消旋破坏。 酶水解不消旋破坏,但水解不彻底
