Chemise' s work is important  because he discovered DNA important to the science we need/know today. Also people who have become doctors or nurses they might need to know this kind of information.]]> 2018-04-04 21:24:39 UTC https://padlet.com/1030070/yl0td6l6guon/wish/248686776 1030070 https://padlet.com/1030070/yl0td6l6guon/wish/249052576 In 1951 Rosalind Franklin was using a crystallography to study DNA. Her work is important because she took the resolution crystallized DNA fibers and looked at the dimensions of DNA strands, with phosphate on the outside of what look to be a helical structure. Her x-ray data was published and on the same issue of Nature as Waston and Crick's introducing their 3D model of DNA structure .]]> 2018-04-05 20:56:23 UTC https://padlet.com/1030070/yl0td6l6guon/wish/249052576 1030070 https://padlet.com/1030070/yl0td6l6guon/wish/249055951 In 1951 Waston and Crick modeled structure of DNA. Their model represented DNA as a doubled helix with sugars and phosphates forming the outer strands of the bases pointing into the center. In 1953 their paper notes that the model "immediately suggests a possible copying mechanism for the genetic materiel. ]]> 2018-04-05 21:11:56 UTC https://padlet.com/1030070/yl0td6l6guon/wish/249055951 1030070 https://padlet.com/1030070/yl0td6l6guon/wish/249058139 The DNA is made of molecule that consists of two strands that wind around one another to form a shape known as a double helix. Each  strand has a backbone made of alternating sugar and phosphate groups.]]> 2018-04-05 21:23:47 UTC https://padlet.com/1030070/yl0td6l6guon/wish/249058139 1030070 https://padlet.com/1030070/yl0td6l6guon/wish/249059423 The nucleotides of DNA are ]]> 2018-04-05 21:29:02 UTC https://padlet.com/1030070/yl0td6l6guon/wish/249059423
