Poly A does not exist in an isolated form in the nucleus and must, therefore, be added to preexisting polynucleotide chains. Thus, when hnRNA molecules have been transcribed, they serve as primer for the biosynthesis of their poly A tail at the 3 -end. Inasmuch as they are no poly (dT) or poly (dA) regions in the DNA, it seems clear that poly A is not synthesized by the traditional transcription mechanisms. Moreover, the enzymes that synthesize poly A are sensitive to cordycepin, which has no or little effect on mRNA synthesis. The enzymes responsible for poly A synthesis have been purified to gel electrophoretic homogeneity from calf thymus in Mary Edmonds laboratory [196]. 

Becquerel, Antoine Henri (1852-1908) A French physicist who accidendy discovered the existence of radioactivity in 1896. By chance, he put away in a drawer some unexposed photographic plates wrapped in black paper. In the drawer there was also a specimen of uranium salt Later, the plates were found to be fogged and led to the conclusion that the uranium had emitted radiation that was sufflciendy powerful to penetrate the wrapping. In 1903 he was awarded the Nobel Prize for physics with Marie and Pierre Curie. His father (Antoine Cesar) and grandfather (Alexandre Edmond) were also eminent physicists and the three held, one after the other, the position of professor of physics at the Musde d Histoire Naturelle from 1837 to 1908.
