MOLECULAR STRUCTURE OF NUCLEIC ACIDS A Structure for Deoxyribose Nucleic Acid We wish to suggest a structure for the salt of deoxyribose nucleic acid(D.N.A.). This structure has novel features which are of considerable biologicalinterest. A structure for nucleic acid has already been proposed by Paulingand Corey (1). They kindly made their manuscript available to us in advanceof publication. Their model consists of three intertwined chains, with thephosphates near the fibre axis, and the …showed first 75 words of 963 total…
