Abstract
Since the discovery of DNA structure in 1953, the deoxyribonucleic acid has always been playing a central role in biological research. As physical and ordered nucleotides sequence, it stands at the base of genes existence. Furthermore, beside this 2-dimensional sequence, DNA is characterized by a 3D structural and functional organization, which is of interest for the scientific community due to multiple levels of expression regulation, of interaction with other biomolecules, and much more. Analogously, the nucleic acid counterpart of DNA, RNA, represents a central issue in research, because of its fundamental role in gene expression and regulation, and for the DNA-RNA interplay. Because of their importance, DNA and RNA have always been mentioned and studied in several publications, and the European Journal of Histochemistry is no exception. Here, we review and discuss the papers published in the last 60 years of this Journal, focusing on its contribution in deepening the knowledge about this topic and analysing papers that reflect the interest this Journal always granted to the world of DNA and RNA.
