Synthesis of Nonribosomal RNA by Lymphocytes: A Response to Phytohemagglutinin Treatment

Abstract
When lymphocytes are stimulated to enlarge and divide by treatment with phytohemagglutinin, most of the rapidly synthesized RNA is nonribosomal. The phenomenon is a response by lymphocytes to stimulation by phytohemagglutinin, rather than a general concomitant of lymphocyte growth.
