Throughout the entire experiment there were many possible ways that the ending result of the appearance of the DNA could have differed. . This is the DNA pieces clumping together. Then alcohol added to the solution causes the DNA to precipitate out. It was established in 1953 by James Watson and Francis Crick that the two strands of their proposed double helis are exact complements of one another, such that the rings of the ladder always consists of either A=T, or G=C base pairs. /Height 155 Water is a molecule of two hydrogen atoms and one oxygen atom (H2O)more. your own essay or use it as a source, but you need In order to extract DNA you must macerate a thumb sized piece of Banana in a zip lock bag.Then weigh out 1.0 gram of salt and 2.0 grams of meat tenderizer the continue maceratingMeasure out 9.0 mL of water and add to the bag.Then continue macerating.See Ms.Leavitt to get 1mL of detergent soap then continue macerating.Once a thick pace called It is also essential for carrying out forensic science, sequencing genomes, detecting bacteria and viruses in the environment and for determining paternity.
