Explanation:
Detailed explanation-1: -Answer and Explanation: Only one strand of DNA is used during transcription because if both strands will transcribe, they will make different mRNA copies that may code for different proteins, and is not possible to make different proteins from single DNA molecules.
Detailed explanation-2: -(1)RNA molecules with different sequences will be produced and hence proteins with different sequences will be produced. (2)double stranded RNA molecules will be produced that would prevent translation of dsRNA.
