  • A codon specifying one amino acid is replaced by a codon specifying another amino acid (correct)
  • A codon specifying one amino acid is copied to another location
  • A codon specifying one amino acid is deleted
  • A codon specifying one amino acid is replaced by a codon specifying the same amino acid
  • What is the main effect of a missense mutation on the genetic code?

  • It deletes the entire gene
  • It increases the number of codons specifying an amino acid
  • It stops the translation of a codon to any amino acid
