Abstract

A method for mapping DNA sequences to specific germinal chromosomes in the ciliated protozoan Tetrahymena thermophila has been developed. This mapping technique (PCR mapping) utilizes the polymerase chain reaction and template DNA derived from nullisomic strains to directly assign micronuclear DNA sequences to specific micronuclear chromosomes. Using this technique, a number of unique sequences and short repetitive sequences flanked by unique sequences have been mapped to four of the five germinal chromosomes.

摘要

已经开发出一种将DNA序列定位到嗜热四膜虫纤毛原生动物特定生殖染色体上的方法。这种定位技术(PCR定位)利用聚合酶链反应和来自缺体菌株的模板DNA,将微核DNA序列直接定位到特定的微核染色体上。利用该技术,一些独特序列和两侧为独特序列的短重复序列已被定位到五条生殖染色体中的四条上。
