Based on structural analysis of the human genome the average size of a gene is 27,000 nucleotide pairs. Given that the average human protein consists of 400 amino acids, what is the minimum length of the mRNA encoding such a protein? Based on your understanding of gene organization in eukaryotes account for the size difference between these two nucleic acids, i.e. explain why the DNA and the mRNA are not the same length.

The average size of a protein in a human cell is about 430 amino acids, yet the average gene in the human genome is 27,000 nucleotide pairs long. With what you know of biology, briefly explain why these numbers are so different.
