Answer:The protein would be made of wrong nuclei acids.
Step-by-step explanation:
*Transcription :This is the synthesis of RNA under the direction of DNA*.
When there is a mutation in the RNA transcript formed, it is known as *error in transcription*and the protein produced due to error in transcription wI'll be made of wrong nucleic acids(RNA or DNA) .
Therefore,when there is an error during transcription, the protein produced would be made of wrong nucleic acids.
