"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."

Deoxyribonucleic acid (DNA) is the hereditary matter in cells that makes up the repository for genes. DNA's structure consists of sugar, phosphate groups,and nitrogenous bases in its nucleotides. These bases are cytosine, thymine, adenine, and guanine. Cytosine and thymine are classified as pyrimidines that have a single ring. Adenine and guanine are classified as purines that have a double rings. Adenine base pairs with thymine (uracil only in RNA), and cytosine base pairs with guanine.

Adenosine triphosphate (ATP) is a complex organic chemical that participates in many processes. Found in all forms of life ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. When consumed in metabolic processes it converts to either the di- or monophosphates respectively ADP and AMP. Other processes regenerate ATP such that the human body recycles its own body weight equivalent in ATP each day. It is also a precursor to DNA and RNA. From the…

proper Italian gelato recipes: triple chocolate, peach, and strawberry

3 Italian Gelato Recipes— Triple chocolate, peach and strawberry, all starting with a basic custard cream gelato recipe.

My life, literally and figuratively.  Glad someone else calls them "nitrogenous base"s and has the directionality of the riboses and number of H-bonds right.    Just realized it's originally from IDT.  That explains it!

DNA is a polymer of nucleotides. Two polymers can join to form a double-stranded molecule (double helix) via complimentary base pairing. For more details go to the "DNA structure and function" board

This DNA is a teaching model; It demonstrates different structural units of DNA: Phosphorus, Oxygen, Deoxyribose, CH2 group, 4 types of nitrogenous bases and bonding molecules of hydrogen. Each unit is shape and color coded.

Drawing this picture helped me as a visual learner to learn the structure of DNA. By drawing a DNA strand I learned that the backbone of DNA is a chain of sugar and phosphate. Linked to the sugar of the chain is one nitrogen base. The nitrogen bases are thymine, guanine, cytocine, and adenine. This chain of sugars phosphates and nitrogen bases are connected to another chain by a hydrogen bond.

Complementary base pairs: purine-pyrimidinepairs; sugar-phosphate backbone; 2 DNA strands wound around one another to produce a double helix; stabilized in part by hydrogen bonds between nitrogenous bases on either strand; due to the geometry of the bases & amount of space available in helix, H bonds only form when A and T w/ 2 bonds or G and C w/ 3 bonds line up on opposite strands
