端粒酶rna meaning in English
telomerase rna
Examples
- ( 2 ) effects of the expression of telomerase rna gene on the telomerase activity in human normal peripheral blood leukocytes , cell growth and cell proliferation
利用基因工程技术从hela细胞中克隆了人端粒酶rna组分( htr )基因。 - We concluded that excessive expression of exogenous htr gene may compete with the endogenous telomerase rna and prevent rna template from combining with telomeric dna , thus repressing the elongation of telomeric dna ( telomeres ) and causing cell aging and cell death . - 6 - 3 . some modifications have been made to overcome the limitation of conventional telomeric repeat amplification protocol ( trap ) assay
分析其原因，可能是htr基因的过表达在数量和空间效应上同细胞内的端粒酶rna组分产生竟争，一定程度上阻碍了端粒酶rna模板区与端粒dna的结合，从而抑制端粒dna的延伸，导致细胞凋亡。 - Telomerase is a ribonucleoprotein complex ( rnp ) composed by its rna component and protein subunits . telomerase can synthesize telomeric dna onto chromosomal ends using its own rna component as a template , elongate the length of telomere , increase cell life and even induce cell immortalization
端粒酶( telomerase )是由端粒酶rna和蛋白质组成的一种核糖核蛋白复合物( rnp ) 。端粒酶含有引物特异识别位点，能以自身rna为模板，逆转录合成端粒dna并加到染色体末端，使端粒延长，从而延长细胞的寿命甚至使其永生化。
