Kinetics of Incorporation of Uridine-c14 into L Cell Rna.

Abstract

Five components have been isolated from L cells by a combination of phenol extraction procedures and sedimentation analysis through sucrose gradients. These components are identified by their sedimentation rates. The 50S and 40S components are derived from the nucleus, the 32S and 18S from ribosomal RNA, and the 4S fraction is the soluble RNA of the cell. L… (More)
