6. cytosine

7. thymine

*Just took quiz

Answer 2

deoxyribose sugar molecules, adenine phosphate, cytosine, thymine

Step-by-step explanation:

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
