You make some RNA in vitro by adding some NTPs into a tube. You want to reproduce some of the work that led to an understanding of how the genetic code works. You mix two nucleotides together in a 3C to 1G ratio.

a) List all the codons that could be found in your RNA and the relative proportions of each.

b) If you added the RNA you have made to an in vitro translation system, what amino acids could be found in the resulting proteins and in what proportions?
