KROK 1 2021 – Question 3 · KROK (Medicine) · Biology
The initiation of transcription process becomes possible when an enzyme DNA-dependent RNA polymerase attaches to a certain segment of DNA molecule. Name this DNA segment:
- A. Terminator
- B. Promoter
- C. Regulator
- D. Repressor
- E. Suppressor
Hint
Think about the specific nucleotide sequence upstream of a gene that is recognised by RNA polymerase and its initiation factors so that RNA synthesis can start.
