Abstract
SUMMARY: Determinations of the cellular content of RNA, total protein and dry weight of Euglena gracilis at different times during logarithmic growth indicated that these parameters did not reflect the constant reproductive rate of these organisms during this period of growth. During exponential growth, the RNA content was reduced by 37 %, the total protein by 45 % and the dry weight by about 76 %. In addition, the RNA and protein content of Euglena showed a similar pattern of decline as growth progressed; the DNA content, however, remained constant throughout the logarithmic growth phase.Keywords
