• B
  $DNA \xrightarrow{\text{Transcription}} m-RNA \xrightarrow{\text{Translation}} \text{protein}$
• C
  $RNA \xrightarrow{\text{Replication}} DNA \xrightarrow{\text{Transcription}} \text{protein}$
• D
  $RNA \xrightarrow{\text{Transcription}} m-RNA \xrightarrow{\text{Translation}} \text{protein}$
