6. Name the 6 chemical parts that bond together to create a DNA molecule?

Nitrogen bases bond to deoxyribose sugars in the backbone. Nitrogen bases bond to each other in pairs A-

T, and C-G. Phosphate bonds between deoxyribose sugars in the backbone.

7. What are the parts of a nucleotide?

A nucleotide consists of one nitrogen base, one deoxyribose sugar, and one phosphate group.
