| Abstract: | The RNA associated with poly(A) sequences from Euglena gracilis and Vicia faba has been isolated by binding to millipore filters and characterized by sedimentation velocity centrifugation and electrophoretic mobility. Poly(A)-associated RNA as isolated in solution was highly aggregated. When denatured, it sedimented as a broad peak with a mean value of 16-18 S. This RNA was shown to be covalently linked to poly(A) sequences which are 150-250 nucleotides long. Our size estimates for plant poly(A) and poly(A)-associated RNA are similar to those obtained for animal cells. |
