This is a math question. really. So I have 6 codons. Leu-Asp-Phe-Ile-Pro-Cys. Now as we've all learned from highschool biology, codons are made up of 3 base pairs each. We've also learned that the genetic code is degenerative, that is, more than one combination of base pairs can mean one single codon. Leu has 4 different posisble combinations Asp has 2 Phe has 2 Ile has 3 Pro has 4 and Cys has 2 The question is now, as you've probably guessed, to determine the number of possible ways to get Leu-Asp-Phe-Ile-Pro-Cys. I'd rather not draw it out. Is there a good equation I could use/way to go about this?
