WebCycloheximide (1 microgram/ml) inhibits incorporation of uridine into RNA of P1798. … Transcription of rRNA and 5 S RNA genes was inhibited by 90% after 2 h and 50% inhibition occurred within 20-30 min. Transcription of the tRNA gene was inhibited 75% after 2 h with a half-time of approximately 1 h. Why is cycloheximide added to the medium?
WebA concentration of cycloheximide which inhibits protein synthesis permits less than one-third of each flagellum to form when both flagella are amputated. When only one is amputated in cycloheximide, shortening proceeds normally and the degree of elongation in the amputated flagellum is greater than if both were amputated in the presence of ...

WebAmong the known inhibitors of eukaryotic translation is cycloheximide (CHX, 1), the most common laboratory reagent used to inhibit protein synthesis (Fig. 1). CHX has been … WebCycloheximide acts at the large subunit of the ribosome to inhibit translation. Here we report that ubiquitin levels are critical for the survival of Saccharomyces cerevisiae cells in the presence of cycloheximide: ubiquitin overexpression confers resistance to cycloheximide, while a reduced ubiquitin level confers sensitivity.
