A temperature sensitive mutant of Escherichia coli which fails to recover from prolonged carbon starvation, was found to be irreversibly killed by exposure to a nonpermissive temperature (43 degrees C), with a half-life of about half an hour. This bacteriocidal effect of the temperature could be rev

A method is described whereby bacterial mutants (sun) may be selected which are able to specifically suppress mutations in the N gene of bacteriophage lambda. The sun mutations seem to be allelic to suA mutations, which suppress the polarity of nonsense codons, since suA mutants have all of the prop
We have previously demonstrated that the sequence 5'TGGCAA 3' located at codons 32-33 of the rIIB gene of bacteriophage T4 is a hotspot for transition mutations (Nelson et al. 1981). Here I report the properties of the same TGGCAA sequence introduced into the gene at codons 11-12. The sequence is hi
