WebAzotobacter polynucleotide phosphorylase was used to prepare short polyadenylic acid messengers with one cytidine residue at the 3′-end. These polynucleotide messengers produced water-soluble lysine polypeptides with COOH-terminal asparagines, thus confirming that the polynucleotide message is read from the 5′- to 3′-end. lauren missing armWebFigure 6.1 A Polynucleotide chain Two nucleotides are linked through 3 '-5 ' phosphodiester linkage to form a dinucleotide. More nucleotides can be joined in such a manner to form a polynucleotide chain.
