Which one of the following a wrongly matched?

  • Transcription - Writing information from DNA to t-RNA

  • Translation - Using information in m - RNA to make protein

  • Repressor protein - Binds to operator to stop enzyme synthesis

  • Operon- Structural genes, operator and promoter

Solution

A.

Transcription - Writing information from DNA to t-RNA

Transcription is a process of RNA synthesis from a DNA template. It involves three main events, i.e., initiation (binding of RNA polymerase to as DNA), elongation (development of a short stretch of DNA) and termination (recognition of release of RNA polymerase). Expect trans cuiprion are correctly matched.
