KROK 1 2017 – Question 148 · KROK (Medicine) · Biological Chemistry
Streptomycin and other aminoglycosides prevent the joining of formylmethionyl-tRNA by bonding with the 30S ribosomal subunit. This effect leads to disruption of the following process:
- A. Translation initiation in procaryotes
- B. Replication initiation in procaryotes
- C. Translation initiation in eucaryotes
- D. Transcription initiation in procaryotes
- E. Transcription initiation in eucaryotes
Hint
Use the clues in the stem (ribosomal subunit size, formylated methionyl-tRNA) to decide which organisms and which macromolecular process, DNA, RNA or protein synthesis, is disrupted.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
