What does the process of transcription specifically require?

• A. Amino acids
• B. DNA as a template
• C. Proteins
• D. Ribosomes

Answer: (B)

Transcription is the biological process where information from a segment of DNA is copied into messenger RNA (mRNA). This process specifically requires DNA as a template because it is the sequence of bases in the DNA that guides the synthesis of the complementary RNA strand. During transcription, RNA polymerase binds to the DNA at a promoter region and unwinds the DNA helix. It then synthesizes the RNA strand by adding nucleotides that are complementary to the DNA template strand. This accurate base-pairing is essential for producing the correct mRNA that will later be translated into a protein. The other options, while important in broader biological contexts, do not specifically pertain to the transcription process. Amino acids are involved in translation, proteins play various roles in both transcription and translation but are not the template themselves for mRNA synthesis, and ribosomes are essential for translating mRNA into proteins but do not participate in the transcription process directly. Thus, the requirement of DNA as a template is fundamental to the function of transcription in gene expression.
