Answer: i) Nucleus
Explanation- The nucleus uses the nucleotide sequence of DNA as a template to make mRNA. The enzyme RNA polymerase II catalyses this activity, which requires nucleotide triphosphates as substrates. Transcription is the process of producing mRNA from DNA, and it takes place in the nucleus.
