Let's calculate the difference in nucleotides. The number of difference multiplied by rate of mutations will help to determine how long ago these two species shared a common ancestor.
Species A: GTACCTAAGTTCACCGAATT
Species B: GAACCTAAGGGCACCGAACT
These species differ in 4 nucleotides.
This number should be multiplied <span>by </span>the rate of mutations
Answer:
