Which one of the following is wrongly matched?

  1. A
    Transcription — Writing information from DNA to -RNA.
  2. B
    Translation — Using information in -RNA to make protein.
  3. C
    Repressor protein — Binds to operator to stop enzyme synthesis.
  4. D
    Operon — Structural genes, operator and promoter.

Solution & Step-by-step Explanation

Transcription is the process of copying genetic information from one strand of DNA into RNA ( -RNA, -RNA, or -RNA). However, in the context of gene expression for protein synthesis, it typically refers to the creation of -RNA. The match (A) is the most suspicious as the standard definition focuses on -RNA.
