One strand of the DNA is used as a template to create an mRNA copy. This process is called transcription. An mRNA copy needs to be made because DNA cannot leave the nucleus. Protein complexes separate the DNA helix to allow complementary mRNA nucleotides to bind to the DNA sequence. The pairing of nucleotides is very specific. Use the A, U, G and C buttons to place the correct mRNA nucleotide with each DNA nucleotide.

Mutations are mistakes in the DNA sequence. Use the Edit DNA button to change the entire sequence or click on an individual nucleotide to make an insertion, deletion or substitution mutation. How does changing the DNA sequence change the resulting protein? You can quickly jump between the DNA sequence and final protein by using the Show DNA and Show protein buttons. Are some types of mutations more damaging than others?
