Condensation of DNA by spermine in the bulk and in the bacteriophage capsid : a cryo-electron microscopy study
By using cryo-electron microscopy, we analyzed the morphology and structure of long double-stranded DNA chains condensed upon addition of varying amounts of the tetravalent polycation spermine (polyamine). Experiments have been performed i) with chains diluted in the bulk and ii) with individual cha...
