    • DNA helicase causes the hydrogen bonds in double DNA strands to unwind and expose the nucleotide bases.
    • The template strand is the DNA strand that is used to make mRNA.
    • RNA polymerase joins the free nucleotides together to form a pre-mRNA molecule.
    • RNA polymerase stops binding free nucleotides when it reaches the stop codon, detaches the pre-mRNA.
    • During ion splicing, non-coding introns are removed from pre-mRNA and only functional exons are joined to form mRNA.
