Question
Chapter 27, Problem 4E
Summary Introduction
To explain: The amino acids which are specified by codons that can be changed to a UAG stop codon by a single point mutation.
Concept introduction: The sequence of three mRNA nucleotides that code for the amino acids during the translation process is called codon. Three nucleotides constitute a codon that codes for the single amino acid. The codon where the translation process starts is the start codon, which is known as AUG; it usually codes for methionine. The stop codon terminates the translation process. The stop codons are UAA, UGA, and UAG.
