The P is the ideal start in the top one (1/5-th of all helices start with a P), and after the P it is nearly all AMELK.

The bottom one must be found by the same threading teachnique as in the example listed earlier in this step in the course. You see that S is good one before the helix, G should be before the helix too, etc.
