What do you need help with? One of the biggest things to remember with Punnett squares is that when you cross them you need to make sure the dominant trait (Upper case letter) is in front of the recessive trait (lower case letter)
I'm pretty sure it's condensation.
Codons are triplets of nucleotides (Adenine, Guanine, Cytosine, and Thymine in DNA/ Uracil in RNA) that are part of the genetic code used to translate the information from DNA into proteins. All the information in the code is translated by RNA which reads the code on the DNA in triplets or codons.
So, in this case, the sequence divided into codons would look like this :
