In this paper, which is an extension of a very recent one, we show, in a first part, that starting from RNA, pore exactly, from the detailed atomic composition of its basic components, the four ribonucleotides UMP, CMP, AMP and GMP, full of Fibonacci numbers, we can derive the "One-Number Model" of the genetic code which was introduced by us some years ago, in 2007. In a second and original part, we consider the opposite way, that is, starting from the "One-Number Model", we can recover, in the detail, the atomic composition of the four ribonucleotides, from which we started, and the "circle is complete".
