Document Summary
Dna: indicate the importance of dna in the human body. Dna in the body contains important genetic information that teaches the body how to produce the correct proteins for proper human function. Without dna, the body wouldn"t know how to create cells and therefore bodily functions will not perform: describe the structure and function of dna. Dnas consists of a deoxyribose sugar, phosphate backbone, and nitrogenous base (guanine, cytosine, adenine, thymine). Guanine pairs with cytosine and adenine pairs with thymine. The phosphate forms the length of the ladder while the base pairs and deoxyribose forms the steps of the ladder. In general, dna is a double helix, twisted ladder that is coiled into chromosomes. The function of dna is to encode genetic information that is essential to creating new organisms, cells, and proteins which will then add up to define new bodily functions: describe base pairs and identify the four bases.
