Describe how mRNA is produced in a cell (5 marks)

Double-helix DNA strands are separated by breaking the hydrogen bonds between complementary bases. One strand acts as a template strand which complementary bases bind to (adenine to uracil, thymine to adenine, cytosine to guanine, guanine to cytosine). RNA Polymerase joins together the RNA nucleotides forming pre-mRNA. Introns are removed by splicing to form mRNA.
