Statements 1 and 2 are true; statement 3 is false.

- A nucleotide = phosphate + 5-carbon sugar + nitrogenous base.
- In DNA, all four nucleotides share the same phosphate group and the same 5-carbon sugar (deoxyribose).
- They differ in their nitrogenous bases (adenine, thymine, guanine, cytosine).
