The reproduction of phage T7 in the presence of hydroxylamine (HA) (mutagenesis in vivo) results in the phenotypic suppression of some amber mutants. The presence of O-methylhydroxylamine (OMHA) results in a similar effect, indicating a similar mechanism for the action of the two compounds. Since the rate of reaction of mutagen with nucleoside residues under these conditions in negligibly low, one of the most plausible explanations of this effect is the enzymic formation of modified precursors and their incorporation into bacterial tRNAs or phage-induced RNA.
