MCQ on Transcription in Prokaryotes







In prokaryotes, transcription is the process where RNA polymerase binds to the promoter region of DNA and synthesizes a complementary mRNA strand using one of the DNA strands as a template. This mRNA carries genetic information from DNA and serves as a template for protein synthesis. This is an MCQ on Transcription in Prokaryotes.
