哺乳动物的端粒 (Ｔｅｌｏｍｅｒｅ)是串联的 (ＴＴＡＧＧＧ)ｎ重复系列 ,具有维持染色体末端结构和功能、稳定染色体的作用。端粒酶 (Ｔｅｌｏｍｅｒａｓｅ)是一种核糖核旦白酶 ,其功能是合成端粒。端粒和端粒酶在染色体畸变形成中特别在通过放射诱导染色体ＤＮＡ损伤或染色单
Mammalian telomeres (Telomere) are tandem (TTAGGG) n repeats with the function of maintaining the structure and function of chromosome ends and stabilizing the chromosomes. Telomerase is a ribulose protease whose function is to synthesize telomeres. Telomeres and telomerase are particularly important in chromosomal aberrations in inducing chromosomal DNA damage or staining by radiation
