Abstract
Toroidal winding of double-stranded DNA in the protein capsids of bacteriophages has been proposed previously. An alternative model for the packaging and arrangement of DNA in bacteriophage capsids is presented here. By introducing sharp folds, the alternative model avoids toroidal winding and its accompanying difficulties. This alternative model is in agreement with the current data obtained with several different bacteriophages.
摘要
此前有人提出噬菌体蛋白质衣壳中双链DNA呈环形缠绕。本文提出了一种噬菌体衣壳中DNA包装和排列的替代模型。通过引入急剧折叠，该替代模型避免了环形缠绕及其伴随的难题。此替代模型与通过几种不同噬菌体获得的当前数据相符。
