... An enzyme called RNA polymerase opens the two strands of the DNA molecule and hooks together the RNA nucleotides as they base-pair along the DNA. RNA polymerase can only assemble the polynucleotide chain from the 5’ → 3’ direction but they don’t need priming to start the assembling. ONLY THE 3’ 5’ ...
