RNA polymerase synthesizes a new RNA strand in which direction?

Explanation:
RNA polymerase builds the RNA chain by adding nucleotides to the 3' end of the growing strand. Each incoming ribonucleotide is joined to the 3' hydroxyl of the last nucleotide, forming a new phosphodiester bond and releasing pyrophosphate. Because attachment happens at the 3' end, the chain grows in the 5' to 3' direction. The enzyme reads the DNA template in the 3' to 5' direction and makes an RNA strand that is complementary to the template (with U instead of T).
