There is a paradox for the difference in the number of protein-coding genes and the number of proteins produced by those genes in the human genome. Describe the paradox and explain how modern genetic discoveries have helped resolve this paradox. In your explanation, be sure to include a real biological (genetic) mechanism, summarize how the mechanism works and why it (partially) resolves this paradox.
