8vo. 437-463 pp. Figs. Printed wrappers. Signature of Norman Horowitz. Fine. RARE. The Study of the Role of RNA in the Transfer of Genetic Information. / Francois Gros was the co-discoverer of messenger RNA who also advanced French life sciences. The year 1961 marked an important stage in Gros' work. Invited by Professor James Dewey Watson to come and carry out a research internship in his laboratory at Harvard University, he managed to demonstrate, for the first time with researchers from this laboratory, the existence of messenger RNA. intermediaries . . . In 1963, Francois Gros was offered the leadership of the microbial physiology department of the Institute of Physico-Chemical Biology in Paris. There, joined by various researchers from the United States, he continued his work on messenger RNA (1963-1968) and demonstrated with his colleague Michel Revel (1966) the existence of proteins also called "initiation factors". à » playing a major role in the "start" of genetic translation within cells (protein synthesis in contact with messenger RNA and ribosomes). / "The visit of Francois Gros in the spring of 1960 was crucial in focusing attention on messenger RNA." â Â" James D. Watson, "The involvement of RNA in the synthesis of proteins," Nobel Prize lecture. / "For Crick, four kinds of information transfer clearly existed: DNA [arrow right] DNA (DNA replication), DNA [arrow right] RNA (the first step of protein synthesis), RNA [arrow right] protein (the second step of protein synthesis) and RNA [arrow right] RNA (RNA viruses copying themselves). There were two steps for which there was no evidence but that Crick thought were possible . . . DNA [arrow right] protein (this would mean RNA was not involved in protein synthesis) and RNA [arrow right] DNA (structurally possible, but at the time, there no was no perceptible biological function)." â Â" Cobb. à « Dans son livre Les secrets du gene, Francois Gros rapporte qu'il a obtenu avec Shiro Naono, dans le laboratoire de Jacques Monod, des rà  sultats qui, eux aussi, indiquent l'implication d'un ARN, de renouvellement tres rapide, dans la synthese protà  ique bactà  rienne?; ils sont publià  s en 1960, en francais, dans les Comptes Rendus de l'Acadà  mie des sciences. à » â Â" Christine Petit, à « Francois Gros (1925â Â"2022), à » Comptes Rendus.
