We have cloned a functional centromeric DNA sequence from Saccharomyces cerevisiae. Using the 2 mu chromosome-loss mapping technique and meiotic tetrad analysis, we have identified this DNA sequence as the centromere of chromosome V (CEN5). The CEN5 sequence has been localized on an 1,100-base-pair BamHI-BglII restriction fragment. Plasmids containing CEN5 and an autonomously replicating sequence are mitotically stable in S. cerevisiae and segregate in a Mendelian fashion during meiosis.
我们从酿酒酵母中克隆了一个功能性着丝粒DNA序列。利用2μm染色体丢失定位技术和减数分裂四分体分析,我们已将此DNA序列鉴定为第五条染色体(CEN5)的着丝粒。CEN5序列已定位在一个1100碱基对的BamHI - BglII限制性片段上。含有CEN5和自主复制序列的质粒在酿酒酵母中进行有丝分裂时是稳定的,并且在减数分裂过程中以孟德尔方式分离。
