  This work presents a mathematical model that establishes an interesting
connection between nucleotide frequencies in human single-stranded DNA and the
famous Fibonacci's numbers. The model relies on two assumptions. First,
Chargaff's second parity rule should be valid, and, second, the nucleotide
frequencies should approach limit values when the number of bases is
sufficiently large. Under these two hypotheses, it is possible to predict the
human nucleotide frequencies with accuracy. It is noteworthy, that the
predicted values are solutions of an optimization problem, which is commonplace
in many nature's phenomena.
