If an exercise asks for the number of informational rna nucleotides, does stop, nonsence codone (3 nucleotides) count?
For example, if we have 300 amino acid in protein, do we count nucleotides of rna like 300×3+3 or just 300×3 and why so?? I dont get it, cause nonsence triplet is also a part of rna right?

I said it was false because I think the original allele can be recessive and also I think it means that mutation will become fixed.
