Introduction telomerase is a ribonucleoprotein reverse transcriptase that synthesizes telo - meric dna sequences using its rna as template . it can remedy the loss of te - lomere after cellular mitosis , maintain telomere length and stabilize chromosome 前言端粒酶( telomerase )是一种核糖核蛋白逆转录酶，能以自身的rna为模板，从头合成染色体末端的端粒dna ，弥补细胞分裂时端粒dna的丢失，维持端粒的长度并稳定染色体。
