RT Journal Article SR Electronic(1) A1 Kay, D.YR 1962 T1 The Nucleic Acid Composition of Bacteriophage øR JF Microbiology, VO 27 IS 2 SP 201 OP 207 DO https://doi.org/10.1099/00221287-27-2-201 PB Microbiology Society, SN 1465-2080, AB SUMMARY: Bacteriophage øR was prepared and purified in sufficient quantity to determine the composition and base ratios of its nucleic acid. The ratios are such that the complementary double-stranded structure usually found in deoxyribonucleic acid (DNA) seems unlikely to be present. This observation and the accessibility of the DNA of phage øR to the action of formaldehyde support the view that phage øR, like phage øX-174 which it resembles, carries its nucleic acid in a single strand., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-27-2-201
