During transcription, which stage involves RNA polymerase moving along the DNA adding nucleotides to the growing RNA strand?

Explanation:
During transcription, after the initial setup at the promoter, the elongation stage is when RNA polymerase moves along the DNA template and adds ribonucleotides to the growing RNA strand. It travels 3' to 5' along the DNA, synthesizing RNA in the 5' to 3' direction, with each new nucleotide being complementary to the DNA template. This is the phase where the RNA chain length increases as nucleotides are continuously incorporated. Termination ends transcription, and processing refers to later RNA maturation steps, not the synthesis itself.
