Ochre mutants, a new class of suppressible nonsense mutants
Journal of Molecular Biology, 1965Suppressors of a strongly polar mutant of the lac gene in Escherichia coli also suppress mutants of the rII genes of bacteriophage T4. Included amongst this set are some amber mutants, but there are also many other mutants which are not suppressed by amber suppressors. These mutants are denned as ochre mutants, and the suppressors as ochre suppressors.

Mutation is the practice of automatically generating possibly faulty variants of a program, for the purpose of assessing the adequacy of a test suite or comparing testing techniques. The cost of mutation often makes its application infeasible. The cost of mutation is usually assessed in terms of the number of mutants, and consequently the number of ...

Science fiction films of the 50s, the period when nuke-awareness was at its height, are full of monsters. And the monsters tend to be radioactive. Peter Biskind, quoted above, tries to reduce the monster movies of the 50s to expressions of the oldest theme in the horror cannon, nature run amok, but monsters are rarely as simple as they at first seem ...

At present, the zebrafish Danio rerio is the only vertebrate species for which a large-scale mutagenesis effort to identify developmental genes has been reported. Several laboratories are now intensely pursuing the molecular characterization of the genes affected by these mutations.

Host range mutants and semitemperate mutants of bacteriophage T3
Virology, 1957Abstract Host range mutants of phage T3 are produced in the phage yield from irradiated bacteria or from some exceptional infected bacteria, or “lasting complexes,” in which lysis is long delayed. In these complexes, phage development is arrested at a stage later than establishment of infection but prior to the appearance of mature phage.

Abstract Many of the basic facts about plant hormones are still obscure, including biosynthetic pathways and their regulation. Furthermore, our knowledge of the molecular steps between hormones and their action is extremely limited. The increasing collection of isogenic genotypes differing in hormone synthesis or responses offers great promise for ...

ON the Government Farm at Dharwar, Bombay Presidency, India, I have for several years had under observation pure lines of cottons of several species and varieties. One of these was Wagale, a Burmese variety of Gossypium neglectum Tod. From 1919 this variety has been self-fertilised, and only the self-fertilised, seed used for sowing in each generation,
