1940年代以来的研究表明,除某些病毒以外,DNA是一切生命形式的遗传物质。正常细胞的DNA修复系统是修复损伤、维持细胞遗传特性相对稳定的重要机制。近年来,DNA损伤修复的研究已成为探讨衰老变化的重要课题。
Research since the 1940s shows that DNA is the genetic material of all life forms except for some viruses. The DNA repair system of normal cells is an important mechanism to repair the damage and maintain the relative stability of cytogenetic properties. In recent years, DNA damage repair research has become an important issue to explore changes in aging.
