What is the correct sequence of transcription?

RNA ------> DNA
DNA ------> Protein
DNA ------> RNA
Protein ------> RNA

The correct answer is: DNA ------> RNA

The correct sequence of transcription is DNA to RNA. In the process of transcription, the information encoded in DNA is copied into messenger RNA (mRNA) by the enzyme RNA polymerase. This step is essential for gene expression, as mRNA serves as a template for translation, where the sequence of nucleotides in the mRNA is used to build proteins. This is a fundamental concept in molecular biology, illustrating how genetic information flows within a biological system. The transcription process initiates when RNA polymerase binds to a specific region of the DNA, known as the promoter, and proceeds to synthesize a complementary strand of RNA using one of the DNA strands as a template. The other options do not correctly represent the transcription process. RNA transcribing back to DNA or directly producing proteins highlights different biological mechanisms like reverse transcription or translation, respectively, which are not part of the transcription process itself. Thus, the accurate flow of genetic information is crucial for understanding various cellular functions and mechanisms in microbiology.
