Abstract
Nucleoids from Salmonella typhimurium strain LT2 consist of supercoiled deoxyribonucleic acid structures that are ribonuclease labile sedimenting at 1,700S. More than 90% of the covalently closed circular deoxyribonucleic acid of a cryptic plasmid harbored by this strain cosediments with the host's 1,700S nucleoids.
摘要
鼠伤寒沙门氏菌LT2菌株的类核由超螺旋脱氧核糖核酸结构组成，这些结构对核糖核酸酶敏感，沉降系数为1700S。该菌株携带的一种隐蔽质粒的共价闭合环状脱氧核糖核酸中，超过90%与宿主的1700S类核共同沉降。
