The messenger RNA of Escherichia coli polyribosomes was analyzed by a variety of
methods for the presence of sequences of polyadenylic acid. No such sequences were …

IT is commonly assumed that the messenger RNA (mRNA) of prokaryotes lacks the poly (A)
sequences which characterise the 3′ terminus of most mRNA of eukaryotes. A report of the …

Department of Biological Sciences, Columbia University, New York, NY 10027 mRNAs in
eukaryotic cells, as every fresh-man biology student of the last 20 or so years has learned …

Pulse-labeled RNA isolated from E. coli cells grown on limiting phosphate medium and
phosphate-containing medium was analyzed by oligo (dT)-cellulose chromatography and by …

The presence of polyadenylate sequences at the 3'-end of mRNA was first observed in
eukaryotic cells about 25 years ago (Darnel1 et al., 1971; Edmonds et al., 1971; Lee et al …

The population of poly (A) chains obtained from yeast spheroplast RNA contains molecules
ranging from about 20 to 60 nucleotides in length. Poly (A) contain-ing RNA obtained from …

JR Greenberg* abstract: It has been found that centrifugation of (ethylenediamine)
tetraacetic acid dissociated L-cel! polyribosomes at 25 C through preformed CS2SO4 …

Polyadenylate sequences are found covalently linked to yeast mRNA molecules. The poly
(A) sequences are relatively homogeneous in size and have an average chain length of …

As a starting point for the study of the biosynthesis of polyadenylated RNA in bacteria, the
characteristics of RNA synthesis by cells of Escherichia coli B made permeable to small …

Publisher Summary This chapter describes that the poly (A) segment in mRNA provides a
dramatic example of an accessory polynucleotide sequence that is clearly not involved in …
