All the following statements about DNA are true, EXCEPT: O DNA is a double-helix, consisting of a sugar-phosphate backbone. O DNA is made up on nucleotides, which consist of one sugar, one phosphate, and one base. O DNA consists of 4 bases - adenine, uracil, cytosine, and guanine. O The two main functions of DNA are to replicate itself and to create proteins (by providing the template for protein synthesis). O The sugar in DNA is deoxyribose.
