KROK 1 2007 – Question 8 · KROK (Medicine) · Biological Chemistry
Examination of a patient revealed reduced contents of magnesium ions that are necessary for attachment of ribosomes to the granular endoplasmatic reticulum. It is known that it causes disturbance of protein biosynthesis. What stage of protein biosynthesis will be disturbed?
- A. Termination
- B. Translation
- C. Aminoacid activation
- D. Replication
- E. Transcription
Hint
Magnesium stabilizes ribosomal subunits; think which major stage of gene expression is carried out on ribosomes, using mRNA as the template, as opposed to events in the nucleus.
