## Abstract The rate of NAD turnover in microplasmodia of __Physarum polycephalum__ was investigated using a double labeling technique with (^14^C)โadenine or adenosine and (^3^H)โnicotinamide. The halfโlife of an NAD molecule in __Physarum__ was estimated to be 25 min, which is shorter than in ei

## Abstract Homogenates of __Physarum polycephalum__ incorporate [^3^H] dATP into nuclear DNA at an initial rate of approximately 15% of the in vivo rate. To attain this level of synthesis, cultures are homogenized in a medium containing Mg^++^, EGTA, glucose and spermine. Incorporation is strongly
## Abstract The conversion of the uninucleate amoebal form of Physarum polycephalum to the multiโnucleate plasmodial form is under the control of a genetic region which contains __matA__ (or __mt__), a determinant of mating specificity. The region is the site of most __gad__ mutations, which give a
Genetic analysis of cycloheximide-resistant mutants has shown that at least three genes control the resistance to cycloheximide in Podospora anserina and that the antibiotic resistance is recessive to sensitivity. In vitro and in vivo studies of protein synthesis indicated that for two mutants cyclo
Axenomycin inhibits protein synthesis in vivo and in vitro in Saccharomyces cerevisiae. The antibiotic acts by binding to ribosomes, most probably to the large ribosomal subunit. Mutant strains resistant to axenomycin appear to contain ribosomes that are not inhibited by the antibiotic. The responsi
## Abstract The Doppler optical coherence tomography technique was applied to image the oscillatory dynamics of protoplasm in the strands of the plasmodium of slime mould __Physarum polycephalum__. Radial contractions of the gelโlike walls of the strands and the velocity distributions in the solโli
