Etiolated Euglena gracilis cells can form chloroplasts in the absence of growth and without the net synthesis of protein and ribonucleic this process, approximately 17% of the cellular. One of these active processes is protein synthesis, a universal function in which RNA molecules direct the synthesis of proteins on ribosomes. This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to .

The conclusions drawn from comparative studies of cytochrome c structures which indicate a close phylogenetic relatedness between Euglena and the trypanosomatid protozoa are supported by the.

Abstract Studies on RNA synthesis and the regulation of gene expression in nuclei are hampered by the complexity of the template. Another eukaryotic transcription system is that of the cellular organelles (mitochondria and chloroplasts), whose genomes are small and well defined.
We have focused our attention on the transcription of these by: 2. added significance in light of studies with actinomycin Dwhich suggest that RNA synthesis is required for the normal operation of the clock (5).
