DescriptionElliptical Genetic Code.JPG	Simplified diagram showing codon bias in hydropathy - molar volume space. This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Elliptical Genetic Code.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. This diagram image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}. For more information, see {{BadJPEG}}. The strongest components (bias) for the encoding of anino acid residues are, in order: C in 2nd position = small size, medium hydropathy U in 2nd position = average size, hydrophobic A in 2nd position = average size, hydrophilic G in 2nd position = outlier Frank Layden (talk) 17:11, 16 October 2013 (UTC) The y-axis is accurate (cubic Angstroms), but the x-axis could have some error from estimates of hydropathy.

I believe this is in error: "U in 1st position = not hydrophilic". That yellow ellipse should be NGN. Please have a look and confirm. I am having this figure redrawn in vector. If you come across this edit, please tell me what to select as a license. This is my first edit on Commons and I need help. Frank Layden (talk) 17:03, 16 October 2013 (UTC)

The Serine codons with G in the 2nd position are properly included if the yellow ellipse is within NGN, which confirms the description is wrong. I am changing it now. Frank Layden (talk) 17:08, 16 October 2013 (UTC)
