Polynucleotide biosynthesis: formation of a sequence of adenylate units from adenosine triphosphate by an enzyme from thymus nuclei.


In spite of recent notable achievements in the isolation and purification of enzymes capable of synthesizing polynucleotides (l-3), the identity of those enzymes responsible for the synthesis of ribonucleic acid in mammalian cells has not been established. The nucleoside diphosphates of the four bases of ribonucleic acid can be polymerized into a… (More)
