Optimal number of spacers in CRISPR arrays

CRISPR performance for two virus species.
Plot of the survival probability E(t) as a function of crRNA decay coefficient δ and the number of spacers S of a cell confronting two different viruses with equal population sizes, ν1 = ν2 = 0.5. The binding efficiency is β = 1 and the interference efficiency is χ = 1.4. Viral mutation probability 1 − μ is equal to 0.1 and rNt = 5.
