著名生物学家谈家桢曾经提出:“如今已有大量事实表明,更本质的生命物质是核酸,而不是蛋白质。”他列举了三点事实依据: 1、病毒的结构很简单,它由蛋白质外壳和里面的DNA(脱氧核糖核酸)组成。病毒繁殖的方式是,通过外壳将DNA注射到寄主细胞中,使细胞在它的控制下,为合成它的核酸和蛋白质服务。最后,这些核酸和蛋白质装配成许多子代病毒,杀死细胞,破门而出。子代病毒外壳的形状和原来病毒的那个躯壳一模一样。事实表明,一切生命体的表现形式,是蛋白质结构的反映。但是,必须有一定结构的DNA,才会产生一定结构的蛋
Tan Jiazhen, a well-known biologist, once said: “There are a large number of facts that have shown that the more essential living matter is nucleic acid, not protein.” He cited three facts: 1. The structure of the virus is very simple. It consists of a protein Shell and the DNA inside (DNA) composition. The way the virus propagates is by injection of DNA into the host cell through the outer shell, which allows the cell to serve its nucleic acid and protein synthesis under its control. Finally, these nucleic acids and proteins assemble into many progeny viruses that kill cells and break out. The shape of the progeny virus shell is identical to that of the original virus. Facts show that the manifestation of all living things is a reflection of the structure of the protein. However, there must be a certain structure of DNA, will produce a certain structure of the egg
