Abstract
In a merodiploid strain of Escherichia coli heterozygous for the ribosomal protein genes spc and str, deletions were observed preventing the expression of either gene but permitting the expression of the other. This suggests that the spc and str genes are in separate transcriptional units.
摘要
在核糖体蛋白基因spc和str杂合的大肠杆菌部分二倍体菌株中，观察到缺失现象，这些缺失阻止了任何一个基因的表达，但允许另一个基因的表达。这表明spc和str基因处于不同的转录单元中。
