2. phosphate, sugar, nitrogenous
3. sugar
4. adenine & thymine, guanine & cytosine
5. adenine, guanine
6. 20%
7. double helix
8. Purines (adenine and guanine) are two-ring structures, while pyrimidines (thymine and cytosine) are single-ring structures; this size difference allows them to pair specifically and maintain a uniform width of the DNA double helix.
9. gene
10. hydrogen bonds
