Question

Suppose that the mutation rate per base pair for a genetic locus is 4 Ã 10â8, and that the locus contains 1,500 base pairs. What is the per-locus mutation rate?

A) 4 Ã 10â5
B) 6 Ã 10â5
C) 8 Ã 10â5
D) 4 Ã 10â4

Answer 1

B) 6*10^-5

Step-by-step explanation:

When you want to know the mutation rate per-locus you only have to multiply the number of base pairs of that locus by the mutation rate per base pair. Its a matter of what is the probability that every base pair in that locus could mutate.

(4*10^-8)*(1500)=6*10^-5
