Answer:
The correct answer will be- direction, the RNA polymerase will add nucloetides.
Explanation:
RNA polymer is an enzyme which adds nucleotide complementary to the DNA template strand. The RNA polymerase enzymes attach to the DNA strand at the promoter region which with the help of other factors will start transcription and will form RNA molecule.
The RNA strands are formed with polarity in 5’ to 3’ direction as the RNA polymerase adds the new nucleotide at to the 3' end of the strand. Thus, the RNA polymerase will bind to the strand of the DNA which runs in 3' to 5' direction which is known as the template strand or antisense strand.
Thus, direction, the RNA polymerase will add nucleotides is the correct answer.
