A mutant of Neurospora crassa with an altered repressible acid phosphatase has been
isolated. The enzyme is much more thermolabile than that of wild type, and has an increased …

A mutant of Neurospora crassa, called UW-6, differs from wild type in being partially constitutive
for synthesis of a species of alkaline phosphatase, and also for a species of phosphate …

Bacteriophage φ6 directs the synthesis of 12 proteins in host cells. We previously isolated
nonsense mutants affecting nine of these proteins. We have now found a nonsense mutant …

Five additional mutants of Neurospora crassa have been isolated that lack the repressible
alkaline phosphatase. The mutations in these strains map at a previously assigned locus on …

Leftward transcription in the region of the left attachment site (att) has been found to be
required for the excision of λ prophage, when a helper provides all the necessary excision …

A recurring question posed in recent issues of Orbis has been whether we find ourselves in
