I have these 4 sequences:

```
X: TACCCGAT
Y: TAAACGAT
Z: AAAACGCG
W: AAAACGAT
```

1)I want to define the distance S(u,v) between two sequences u and v to be simply the number of letter substitutions (Hamming distance).

2)Will this distance function S(u, v) be ultrametric on these four sequences?

3) I also need to build the average linkage (a.k.a., UP GMA) tree for these four sequences. and then Bootstrap the above data using 5 replicates and compute the confidence of each branch by using MATLAB.

Can anyone help me?
