A patient’s organism has decreased concentration of magnesium ions that are necessary for attachment of ribosomes to the granular endoplasmatic reticulum. It is known that this causes protein biosynthesis disturbance. What stage of protein biosynthesis will be disturbed?

  1. A. Termination
  2. B. Amino acid activation
  3. C. Translation
  4. D. Replication
  5. E. Transcription
