Correspondence analysis of RSCU for the total genes in Bombyx mori. A) Distribution of the total genes in Bombyx mori on the plane corresponding to the coordinates on the first and second principal axes was shown in Panel A. Orange triangles, purple triangles and gray triangles, indicate genes with a GC content higher than or equal to 60%, more than or equal to 45%, but less than 60% and less than 45%, respectively. Additionally, blue squares indicate the coordinates of ribosome on the first and second principal axes. B) Distribution of codons on the same two axes was shown in Panel B. Codons ending with A, U, C and G are shown in red, green, yellow, and blue, respectively.
