"The proposer of this extraordinary formula for the nucleic acids has not quoted any
significant evidence in support of it. The ligation of five oxygen atoms about each
phosphorous atom is such an unlikely structural feature that the proposed phospho-tri-anhydride
formula for the nucleic acids deserves no serious consideration." Linus Pauling Verner Schomaker. J. Am. Chem. Soc. 74: 1111. 1952.
