    Notes: [Auszug] 8-AZAGUANINE, which differs from guanine in having the carbon atom at position 8 replaced by nitrogen, inhibits the growth of certain bacteria, fungi, algae, protozoa, animal tumours, and some plant and animal viruses. Some evidence'has been presented1 that, in certain of these cases, 8-azaguanine ...

    Polynucleotides from Deoxyribonucleic Acids (1952)

    Notes: [Auszug] We have now isolated these and several other substances from similar digests of wheat embryo deoxyribonucleic acid. This acid was chosen because of its singularly high content of 5-methyl cytosine3 and was prepared via the deoxyribonucleoproteins by the method of Mirsky and Pollister4. The ...

    Evidence for the Existence of Two Types of Ribonucleic Acid (1954)

    Notes: [Auszug] A ribonucleic acid of type I may be considered as being built up of nucleoside 3' phosphates, whereas type II is built up of nucleoside 5' phosphates. For convenience, we shall call those end residues which bear only a phosphate group joining them to the remainder of the chain terminal 'nucleoside ...

    Incorporation of Halogenated Pyrimidines into the Deoxyribonucleic Acids of Bacterium Coli and its Bacteriophages (1954)

    Notes: [Auszug] THE pyrimidine 5-bromouracil may be regarded as a structural analogue of thymine in which the methyl group of thymine is replaced by a bromine atom. Weygand, Wacker and Dellweg1 showed that the inhibition of growth of Streptococcus faecalis R. by 5-bromouracil is competitively reversed by thymine. ...

    Notes: [Auszug] IN the past few years the basic constitution of several ribonucleic acids has been established1"4, but so far there has been little evidence as to the way in which the constituent nucleotides are arranged in the molecules. Hydrolysis of ribonucleic acids by alkali and by cold dilute acids gives ...
