The results of previous in vivo studies indicate that a DNA-free procapsid (capsid I) packages bacteriophage T7 DNA during infection of Escherichia coli. It was shown here that capsid I, isolated by electrophoresis in metrizamide density gradients, packaged DNA and formed infectious phage particles when incubated in vitro with extracts deficient in capsid proteins.
