This DNA Molecule Model comes in two size, they both encode the text "Crick" (After Francis H.C. Crick who discovered, together with James Watson, the structure of the DNA molecule in 1953.)
"Crick" in amino acid code is: Cys, Arg, Ile, Cys, Lys".
"Crick" in DNA code is "TGC, CGT, ATA, TGC, AAG".
Scaling
Small: 1 Angstrom = 1,0 mm
Large: 1 Angstrom = 1,5 mm
I offer DNA Molecule Models in many shapes and sizes, have a look in this DNA shop section.

How coding and decoding works in the DNA Models I offer at Shapeways:
This is the translation code I use to go from a text to a DNA code that is used in the 3D printed Molecule Model: A = Alanine = GCT, B = (Alanine) = GCA, C = Cysteine = TGC, D = Aspartic acid = GAT, E = Glutamic acid = GAG , F = Phenylalanine = TTT, G = Glycine = GGG, H = Histidine = CAT, I = Isoleucine = ATA, J = (Isoleucine) = ATC, K = Lysine = AAG, L = Leucine = CTC, M = Methionine = ATG, N = Asparagine = AAT, O = Pyrrolysine(unusual) = TAG, P = Proline = CCC, Q = Glutamine = CAG, R = Arginine = CGT, S = Serine = TCA, T = Threonine = ACT, U = Selenocysteine(unusual) = TGA, V = Valine = GTC, W = Tryptophan = TGG, X = (Valine) = GTA, Y = Tyrosine = TAC, Z = (Tyrosine) = TAT
This is based on the universal genetic code as explained here on wikipedia. As not all letters of the alphabet are encoded by an ordinairy amino acid, I also use some more exotic amino acids, they are encoding the letters O and U and are indicated above as (unusual). Then still not all leters are covered, so I have used some arbitrary codes, these are the letters B, J, X and Z and are indicated by the amino acids between brackets.
In the case of this specific model that codes "CRICK" however, none of the exotic or arbitrary codes are used, all leters are coded by regular amino acid letters.
Base coloring in the 3D print is according to Nucleic Acid Database (NDB) Atlas:
A = Adenine = Red, C= Cytosine = Yellow, G = Guanine = Green, T = Thymine = Blue.
To decipher the code from the 3D print: Start reading from the strand of which the backbone ends with an orange (phosphor) atom. For horizontal models that leaves two possibilities, you will have to determine at which of the two ends to start. For the vertical models you have to start reading at the top.
