KROK 1 2009 – Question 102 · KROK (Medicine) · Biological Chemistry
You are studying functioning of a bacteria operon. The operator gene has been released from the repressor gene. Immediately after this the following process will start in the cell:
- A. Repression
- B. Transcription
- C. Processing
- D. Replication
- E. Translation
Hint
Ask which step of gene expression is blocked while the repressor occupies the operator, and what becomes possible when it leaves.
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.
