端粒酶 (ｔｅｌｏｍｅｒａｓｅ)是一种能延长端粒末端的核糖核蛋白酶 ,由具有模板功能的ＲＮＡ组分和催化活性蛋白质组分组成。它能以自身ＲＮＡ为模板反转录合成端粒ＤＮＡ序列 (ｔｅｌｏｍｅｒｉｃＤＮＡｓｅｑｕｅｎｃｅ ,ＴＥＬ)添加到染色体末端 ,以补偿细胞分裂时染色体
Telomerase is a ribozyme that extends the telomere end and consists of a template-functional RNA component and a catalytically active protein component. It can reverse transcribe synthesize telomeric DNA sequences (TEL) to chromosome ends using its own RNA as a template to compensate for chromosomes in cell division.
