Going through I have

Pro-Ser-Val-Thr-Stop-Stop-Arg-Thr-Lys-Stop-Asn-Ser-Asn-Gln-Leu-Met-Val-His-Glu-His-Leu-Cys-Try-CG

I'm confused what to do from here. Or which part is important? Also the CG at the end?

Thanks for the update, but how? Please explain. I was looking at the GC at the end, and didn't understand that either Neutral Dummy
