Abstract
Polyadenylated messenger RNA extracted from HeLa cells was hybridized with a mass excess of HeLa DNA. The kinetics of the hybridization reaction demonstrated that most of the messenger RNA is transcribed from nonrepetitive DNA. The amount of messenger RNA hybridized to DNA was measured both with and without prior RNase treatment. Comparison of the results indicates that within the limits of detection, HeLa messenger RNA does not contain repetitive sequence elements covalently linked to nonrepetitive sequence transcripts. However, a small fraction of the HeLa messenger RNA preparation is transcribed entirely from repetitive DNA sequences. This fraction represents about 6% of the total polyadenylated messenger RNA preparation.Mesh:
