DNA MODEL

Model : 55X-DNA

DESCRIPTION-
DNA is a molecule composed of two chains that coil around each other to form a double helix, carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms. A DNA diagram helps represent this double-helix structure and its components. The two DNA strands are also known as polynucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone.

The nitrogenous bases of the two separate polynucleotide strands are bound together according to base-pairing rules (A with T and C with G), with hydrogen bonds (A and T by double bonds and C and G by triple bonds) to make double-stranded DNA. A project DNA model can be used to demonstrate this double-helix structure, while a DNA model project can visually represent the arrangement of its atoms and molecular components.

A total of five types of atoms make up the whole structure of DNA: black represents carbon atoms, red represents oxygen, white represents hydrogen, blue represents nitrogen, and orange represents phosphorus.
