Question: is rna read 3 to 5?
Answer: RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5' to 3' direction, while reading the template DNA strand in the 3' to 5' direction. ... That is, it can only add RNA nucleotides (A, U, C, or G) to the 3' end of the strand.
