A combinatorial approach to the previous problem is possible.

Show that there are 16 five-letter words in the one-mismatch neighborhood of

GCATC (including GCATC itself). How many of these words begin with G? How

many begin with a letter other than G? Use this information to produce the

first column of a PWM.
