Explain mutation effect on protein
A coding DNA sequence in a school molecular model lesson has one base substituted, causing a different mRNA codon and a different amino acid. Explain how this can affect the protein. Enter the answer and choose the interpretation that best matches the biological evidence.
Worked practice: biological evidence and answer
Use the labelled biological evidence first, then connect it to the final answer.
