A DNA sequence segment is initially AAA ATG TGA CCC. Which mutation would have the most significant effect on the resultant protein synthesized?

Question

Quizplus · Accepted Answer

Mutation B changes the start codon (ATG) to ATT, which could prevent the initiation of translation, having a significant impact on protein synthesis. The other mutations alter the sequence but do not affect the start codon or introduce a stop codon.
