During transcription, the RNA molecule is synthesized in which direction?
Show answer and explanation
Correct answer: 5' to 3' using the template strand read in the 3' to 5' direction
RNA polymerase adds nucleotides to the 3'-OH end of the growing RNA chain, making the synthesis direction 5' to 3'. To maintain complementarity, the enzyme must move along the template DNA strand in the 3' to 5' direction.
