Abstract

A find structure map of the EcoRI fragment containing the lambda attachment-site region has been constructed. 38 different restriction endonucleases have been employed and 170 sites located in this fragment. In addition, sites in adjacent regions have been determined for several enzymes. Complete cleavage maps of the entire lambda genome have been obtained for endonucleases BglII, BluI, KpnI, SacI, SacII, SalI and XbaI. The strategy employed for mapping included comparison of deletion and substitution mutants, analysis of mixed digests, and detailed analysis of subfragments.

摘要

已构建了包含λ附着位点区域的EcoRI片段的精细结构图谱。使用了38种不同的限制性内切酶,并确定了该片段中的170个位点。此外,还确定了几种酶在相邻区域的位点。已获得了内切酶BglII、BluI、KpnI、SacI、SacII、SalI和XbaI对整个λ基因组的完整切割图谱。用于图谱绘制的策略包括缺失和取代突变体的比较、混合消化物的分析以及亚片段的详细分析。
