What are the chemical componets of DNA

DNA has three types of chemical component: phosphate, a sugar calleddeoxyribose, and four nitrogenous bases-adenine, guanine, cytosine, and thymine.

DNA has a sugar-deoxyribose, 4 type of nitrogen bases-adenine, guanine, cytosine and thymine and phosophate. The Sugar molecule in DNA is basically a ribose sugar. The ribose sugar is a pentose sugar. The ring consists of four carbon atoms while the 5' C atom is outside the ring Positions 1', 3' and 5' in the right have OH groups while the 2' carbon position has only H. There is no O; hence the sugar is said to be Deoxyribose (no oxygen in the second carbon position).
