To use a genetic sequence as a molecular clock, the changes in nucleotides in the sequence must have accumulated at a steady pace over time. Drawing on what you know about codons and redundancy in the genetic code, which type of change would most likely be the type that is useful for a molecular clock?
A) changes in the first nucleotide pair in the codon
B) changes in the second nucleotide pair in the codon
C) changes in the third nucleotide pair in the codon
D) All of these changes are equally useful for a molecular clock.
