DNA Mini Model
Our DNA Mini Model represents the classic DNA double helix in 4 formats.
The bottom section of this DNA double helix model shows a surface format emphasizing major and minor grooves. Details of the structure of DNA progressively emerge as the model thins, gradually revealing individual atoms in the middle section while highlighting nucleotide bases at the top.
The model transforms from the bottom surface section into a large spacefill format featuring the CPK coloring scheme. The diameter proceeds to gradually decrease to a small spacefill format, finally revealing the individual atoms in the nitrogenous bases. From there the model transforms into a wireframe format at the top, which emphasizes the individual nucleotide bases while retaining its spacefill backbone features.
DNA (deoxyribonucleic acid) is the genetic code for life. It is a double helix with 2 antiparallel strands made up of alternating sugar and phosphate groups. This sugar-phosphate backbone holds the nitrogenous base pairs. There are 4 DNA bases: adenine pairs with thymine and cytosine pairs with guanine. The nitrogenous bases form a code that is replicated and then transcribed to ultimately make the proteins that are essential for life.
The 1962 Nobel Prize in Physiology or Medicine was awarded jointly to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
