Arrangement of double-stranded DNA packaged in bacteriophage capsids. An alternative model.
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.
