Transcription proceeds in the 5' → 3' direction, meaning that the RNA molecule is synthesized by adding nucleotides to the 3' end of the growing RNA chain. The template DNA strand is read and copied in the 3' → 5' direction, resulting in an RNA molecule that has the same sequence as the non-template (coding) strand of DNA but with uracil replacing thymine. RNA polymerization also occurs in the 5' → 3' direction, as the incoming nucleotide triphosphates are added to the 3' end of the RNA chain.
