Abstract
IT has previously been shown1,2 that when rat thymus cells are incubated in the presence of glucose labelled with carbon-14, the isotope is incorporated to a different extent in the ribose moieties of the four individual types of nucleotide derived from ribonucleic acid. The ribose attached to the pyrimidine bases has a specific activity lower than that of the purine-bound ribose. The present report deals with experiments on the sugar component of deoxyribonucleic acid, and also with a comparison of carbon-14-labelling of deoxyribose and incorporation of phosphorus-32 into the nucleotides of deoxyribonucleic acid.
