Final answer:
The diagram can be labeled with nucleotide, deoxyribose, phosphate group, nitrogen base, hydrogen bonds, and base pair.
Step-by-step explanation:
The diagram can be labeled as follows:
- Nucleotide: The building blocks of DNA that consist of a nitrogenous base, deoxyribose sugar, and a phosphate group.
- Deoxyribose: The 5-carbon sugar molecule that is a component of a nucleotide.
- Phosphate group: A molecule made up of phosphorus and oxygen atoms that is a component of a nucleotide.
- Nitrogen base: The part of a nucleotide that contains nitrogen and can be either a purine (adenine and guanine) or a pyrimidine (cytosine and thymine).
- Hydrogen bonds: Weak bonds that form between the nitrogen bases of two nucleotide chains and hold the DNA strands together.
- Base pair: The pair of nitrogen bases that form complementary base pairs in DNA. Adenine always pairs with thymine, and cytosine always pairs with guanine.
