Abstract:
:Analysis of the deoxyribonucleic acid prepared from Proteus mirabilis, Escherichia coli, and Serratia marcescens in an alkaline CsCl gradient has shown that there is an asymmetric distribution of guanine plus thymine residues between the complementary strands of the deoxyribonucleic acid.
