A mosaic made of different colors of maize (corn) kernels depicting DNA. Most kernels were grown in a Cornell research field in the summer of 2012, and they represent some of the natural color variation of maize kernels. The color code is: Green = Guanine (G) Orange = Cytosine (C) Blue = Thymine (T) White = Adenine (A) Starting at the upper left, the full sequence is GCTTCAGAGA, which is part of exon 6 of the maize r1 gene, one of the classic genes that controls color of the maize kernel. The DNA pattern is based off a stained glass pattern available at glasssorcery.com
