Answer: A. The process of making RNA from DNA.
Step-by-step explanation:
The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.
