WebVerified by Toppr. The following points explain the model of DNA as proposed by Watson and Crick: 1. DNA is made up of double helix made up of polynucleotide chains that are coiled with each other in a right-handed fashion. 2. The two strands are anti-parallel to each other. One stand runs in 5'-3' polarity and other runs in 3' to 5' polarity. 3. WebThe original model of DNA structure created by Crick and Watson.

WebThe results from Picture 51 are special in that its results actually show a very defined X-shape. This shows us just a small piece of the DNA, and since DNA repeats in very long chains, we can apply this model to the entirety of the chain. Then, once we account for 3-dimensions, we can conclude it is a double helix. 7. fire cup coffee location
