A strand of dna with the sequence aac aag ccc undergoes a mutation, and the first a is changed to a
c. how will this mutation affect the amino acid sequence?
First write it out: AAC AAG CCC....which are amino acids...ASP LYS PRO If you change the first A to a C you get... CAC AAG CCC...which gives rise to amino acids...HIS LYS PRO Only the first amino acid is changed...but that could be devastating depending on the protein.
