Summary[edit]

Description
English: Simplified diagram showing codon bias in hydropathy - molar volume space.

The strongest components (bias) for the encoding of anino acid residues are, in order:

C in 2nd position = NCN = C2 -> small size, medium hydropathy

U in 2nd position = NUN = U2 -> average size, hydrophobic

A in 2nd position = NAN = A2 -> average size, hydrophilic

U in 1st position = UNN = U1 -> not hydrophilic

where N is any of {A, C, G, U}

The y-axis is accurate (cubic Angstroms), but the x-axis could have some error from estimates of hydropathy.
