A diagram shows the three separate components of a nucleotide and how they are combined to form a complete molecule. A nitrogenous base is represented as a purple hexagon. A sugar is represented as a grey pentagon. A phosphate group is represented as a light brown circle. A cut-away from the generic nitrogen base shows the chemical structure of the three types of pyrimidine bases (cytosine, thymine, and uracil) and the two types of purine bases (adenine and guanine).
"This Double Helix is a scientific model of B deoxyribonucleic acid, which is the most common form of DNA. DNA is a chemical carrier of our genes. It has an elegant geometric structure that allows it to store a massive amount of information. Every organism has its own DNA, and it is our DNA that makes each of us unique. Beads representing Phosphorus and Deoxyribose are 15 mm wide and multifaceted, and beads representing nitrogenous bases are oval and flat, 25 mmX20 mm."
3 Main differences between DNA & RNA: RNA uses the sugar Ribose while DNA uses Deoxyribose. RNA is single stranded while DNA is double stranded. RNA uses the nitrogenous base Uracil whereas DNA uses the nitrogenous base Thymine.
Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.
