Assess the possibility of errors occurring during the stages of protein synthesis, particularly during transcription and translation. Analyse the cause and effect of genetic mutations in DNA, including:
• Missense
• Nonsense
• Silent
• Insertion
• Deletion
• Duplication
• frameshift
Provide examples of the impact that these errors may have on the end products of protein synthesis.
