WebMost temperature-sensitive mutations affect proteins, and cause loss of protein function at the non-permissive temperature. The permissive temperature is one at which the protein typically can fold properly, or remain properly folded. At higher temperatures, the protein is unstable and ceases to function properly. WebJan 1, 1973 · Abstract. Temperature-sensitive mutations in bacteriophage T4 gene 30 (polynucleotide ligase) were examined for their effects on spontaneous and proflavine-induced frameshift mutagenesis in the rII and ac (acridine resistance) cistrons. Only small (fourfold or less) effects on mutation rates were observed, even when selection artifacts …
