HELPPPP!!!!! Which of these are components of DNA? Check all that apply. deoxyribose sugar molecules ribose sugar molecules adenine phosphate molecules uracil cytosine thymine??????

DNA has three types of chemical component: phosphate group, a deoxyribose (5-carbon sugar group), and four nitrogenous bases which are adenine, guanine, cytosine, and thymine. Adenine and guanine are called purine because they have a double-ring structure. Also, cytosine and thymine, have a single-ring structure, hence they are called pyrimidine. The chemical components of DNA are arranged into groups called nucleotides which forms the backbone of the DNA and each consist of a phosphate group, a deoxyribose sugar molecule, and any one of the four bases.

Note: the ribose sugar molecule and uracil are components of RNA
