During transcription, mRNA is synthesized using which molecule as a template?

Explanation:
During transcription, the template is DNA. RNA polymerase reads the DNA template strand and builds a complementary RNA strand in the 5′ to 3′ direction, using ribonucleotides and substituting uracil for thymine. The resulting mRNA is therefore complementary to the template DNA and similar in sequence to the coding (non-template) DNA strand, except for U replacing T. The other options don’t fit because RNA isn’t used as a template for making mRNA in transcription, proteins are synthesized from mRNA during translation, and carbohydrates aren’t involved as templates in this process.
