1. Two 41-character long DNA sequences differ in 6 positions. Admitting that their evolution follows the Jukes-Cantor model, what is the Jukes-Cantor distance between them?
Answer:
The Jukes-Cantor distance can be calculated by the formula
where K is the genetic distance and d is the number of observed substitutions divided by the sequence length. The Jukes-Cantor distance between the two sequences is:
0.1628
