title: Separation of replicative intermediate from single-stranded ribonucleic acid by sedimentation at low ionic strength.
abstract: By sedimentation in 2.5 x 10(-4)m sodium ethylenediaminetetraacetate at 25 C, replicative intermediate could be separated from single-stranded ribonucleic acid, both viral and ribosomal. All of the label in the replicative intermediate after a brief pulse of titrated uridine was resistant to ribonuclease.
