Jyssum, Kaare (University of Oslo, Oslo, Norway). Polarity of chromosome replication in Neisseria meningitidis. J. Bacteriol. 90:1182-1187. 1965.-Relative frequencies of various genetic markers in the deoxyribonucleic acid of Neisseria meningitidis in exponential- and stationary-growth phases were compared by use of a transformation system. On the basis of an analysis of eight genetic markers, including a competence factor, it is assumed that a polarity exists in the chromosome replication. A genetic map has been constructed according to the model of Yoshikawa and Sueoka. Chromosome replication has been compared in genetically competent and genetically incompetent strains. The change from genetic competence to genetic incompetence seems to result in a change in the replication of the chromosome. The results are discussed in relation to findings from other transformation systems, particularly that of Bacillus subtilis.
耶斯姆，卡雷（挪威奥斯陆大学，奥斯陆）。脑膜炎奈瑟菌染色体复制的极性。《细菌学杂志》90:1182 - 1187。1965年。——通过转化系统比较了脑膜炎奈瑟菌在指数生长期和稳定生长期脱氧核糖核酸中各种遗传标记的相对频率。基于对包括感受态因子在内的8个遗传标记的分析，假定染色体复制存在极性。已根据吉川和末冈的模型构建了遗传图谱。对遗传感受态菌株和遗传非感受态菌株的染色体复制进行了比较。从遗传感受态到遗传非感受态的转变似乎导致了染色体复制的变化。结合其他转化系统，特别是枯草芽孢杆菌的研究结果对这些结果进行了讨论。
