生物组织——如 DNA,组成其主要因素的环境条件是放射线和化学物质,当DNA 增加时,由于 DNA 复制过程的误差引起 DNA 分子不断变化,.一部分被破坏、但马上就可自行修复。并以正常的 DNA发挥其功能。这种修复并不限于 DNA。无论是擦伤、切伤,在不知不觉中愈合。生物分子、组织正是这样不断地被破坏、被修复,生物恰恰具有柔软性的柔结 Biological tissues - such as DNA - are the major environmental factors that make up radioactive and chemical substances. As DNA increases, DNA molecules change due to errors in DNA replication processes, some of which are destroyed but can be repaired on their own. And to function as normal DNA. This repair is not limited to DNA. Whether it is abrasions, cuts, heals unknowingly. Biomolecules, organizations, it is so constantly destroyed, was repaired, creatures just have the softness of the knot
