During transcription, which molecules align with the DNA template to form messenger RNA?

Explanation:
RNA nucleotides are the building blocks that pair with the DNA template during transcription to assemble messenger RNA. RNA polymerase brings in these nucleotides (A, U, C, and G) and links them in a growing chain, using base-pairing rules where uracil substitutes for thymine. This creates an RNA copy that is complementary to the DNA template. The other options aren’t used to build the RNA strand: DNA nucleotides would form DNA rather than RNA, and while enzymes and proteins play crucial roles in transcription, they are not the nucleotides that compose the messenger RNA.
