telomere restriction fragments meaning in English

端粒有限长度

Objective through measure telomere length ( mean length of telomere restriction fragment , trf ) of dermal and intramuscular , and study it ' s length correlating with the different human " s age . the trf was examined by southern blotting . the formula to age estimating was obtained by regression analysis between the trf and the age
目的应用southern杂交技术，对皮肤、肌肉端粒dna片断长度( meanlengthoftelomererestrictionfragment ，简称： trf )进行观察，测定不同年龄段人群的端粒dna片断长度值，以期初步探明不同年龄段人群的端粒dna片断长度的变化规律，绘制出端粒dna片断长度值随年龄变化的标准曲线，比较性别、籍贯对端粒dna片断长度的影响，以期为法医实践工作中对无名尸体年龄推断提供理论依据。
