Table 2 RMCU vs. maximum expression and breadth of expression for amino acids with major codons. The (+) sign indicates significant increase. The (-) sign indicates significant decrease, and N.S. indicates non-significant tendency

From: The action of selection on codon bias in the human genome is related to frequency, complexity, and chronology of amino acids
