Relationship between expression amount and codon usage bias
... We examined the relationship between codon usage biases, expression and Ks data from the yeast 2 gene family, multiple gene family and big gene family. We found that in the gene pairs of yeast 2 gene & multiple gene family, if one gene in the pair has a significant large codon usage bias, then the c ...
