Genetic Regulation and the Lactose Operon

ID #1417

I'm slightly confused on something, what is the difference between the two cases? Question (1): How many ATP equivalents are required to translate an mRNA molecule with a 6000 bp coding region? The answer was 6000. Question (2): Your favorite gene has 10,000 nucleotides. Approximately how much energy is needed to make one protein from your favorite gene? - The answer is 20,000. I recognize there is a difference, but would greatly appreciate the professional explanation as to why.

The reason is that one of the questions specifically singles out that it's asking for the amount of energy needed to translate the protein, while the other asks for the total amount of energy it takes to make protein from the gene. So the former excludes transcription, while the latter includes transcription.
