This DNA Molecule Model comes in three size, they all 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". This sequence and text is also printed on the bottom of the stand.
Small: 1 Angstrom = 1,0 mm
Large: 1 Angstrom = 1,5 mm
Extra Large: 1 Angstrom = 2,0 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.
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.
Refering to Francis Harry Compton Crick (8 June 1916 – 28 July 2004) who was a British molecular biologist, biophysicist, and neuroscientist, most noted for being a co-discoverer of the structure of the DNA molecule in 1953 with James Watson and Rosalind Franklin. Together with Watson and Maurice Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
