Messenger RNA (mRNA) is used during translation to form polypeptides. Describe how mRNA is produced in the nucleus of a cell.
mRNA is messenger RNA which carries information from the genome to be translated into proteins. The DNA is transcribed into mRNA in the nucleus. DNA helicase breaks the hydrogen bonds of DNA into sense and antisense strandsRNA bases are attracted to exposed DNA bases following complementary base pair rules (A-U, C-G) RNA polymerase forms pre-mRNA using the antisense strand as a templatepre-mRNA spliced into mature mRNA by removal of introns
