4. (Sheldon Ross) A DNA nucleotide has any one of four values {A, G,C,T). A standard model for a mutational change of the nucleotide at a specific location on the DNA strand, is a Markov model that assumes that from one time step to the next, the probability that the nucleotide remains unchanged equals 1-3α, for some α, 0 < α < 1 . If it does change (i.e., the nucleotide undergoes mutation), then it can change to any of...

2. Problem 2.5. Consider a random walk on 10..... which movies left and right with respective probabilities a and p. If the walk is at 0 it transitions to 1 on the next step. If the walk is at k it transitions to k-1 on the next step. This is called random walk with reflecting boundaries. Assume that k 3, =1/4, p = 3/4, and the initial distribution is uniform. For the following, use technology if needed. (a) (10.1.X2 }...
