Question

match the letter from image above to the component of dna:
column a\t\t\tcolumn b

1. ___ deoxyribose (sugar)\t\ta. d
2. ___ hydrogen bonds\t\tb. f
3. ___ nucleotide\t\t\tc. e
4. ___ phosphate\t\t\td. b
5. ___ nitrogenous base pair\te. a
6. ___ covalent bond\t\t\tf. c

Explanation:

1. Deoxyribose (sugar) is part of the nucleotide structure, and in the DNA diagram, the sugar component is labeled D.
2. Hydrogen bonds hold the nitrogenous base pairs together, and in the diagram, the hydrogen bonds are labeled C.
3. A nucleotide consists of a sugar, phosphate, and nitrogenous base, and the labeled B represents a nucleotide.
4. Phosphate is a component of the nucleotide, and in the diagram, the phosphate is labeled E.
5. Nitrogenous base pair is held by hydrogen bonds, and the base pairs are labeled F.
6. Covalent bonds are in the sugar - phosphate backbone, and the covalent bonds are labeled A.

Answer:

1. Deoxyribose (sugar): a. D
2. Hydrogen bonds: f. C
3. Nucleotide: d. B
4. Phosphate: c. E
5. Nitrogenous base pair: b. F
6. Covalent bond: e. A
