Answer:

1. Deoxyribose (sugar) is part of the nucleotide structure and in the DNA diagram, the sugar component is labeled as F? Wait, no, let's recall DNA structure: A nucleotide has sugar (deoxyribose), phosphate, and nitrogenous base. The sugar - phosphate backbone has sugar (deoxyribose) and phosphate. Looking at the labels, Deoxyribose (sugar) should match with F? Wait, no, let's go step by step:

• 1. Deoxyribose (sugar): In the DNA structure, the sugar (deoxyribose) is part of the nucleotide and in the diagram, the label for sugar is F? Wait, no, let's check the standard DNA structure. The nucleotide has a sugar (deoxyribose), phosphate, and base. The sugar - phosphate backbone: the sugar is connected to phosphate. Looking at the options, Deoxyribose (sugar) should be matched with F? Wait, the options for 1 are a - f. Wait, the first row: Column A 1. Deoxyribose (sugar), Column B options: a. D, b. F, c. E, d. B, e. A, f. C. Wait, maybe I made a mistake. Let's recall:
• Deoxyribose (sugar): In the DNA diagram, the sugar is part of the nucleotide. The label for sugar (deoxyribose) is F? Wait, no, let's think again. The nucleotide is the basic unit, which has sugar, phosphate, and base. The label B is the nucleotide? No, B is the nucleotide? Wait, the red circle is a nucleotide, so B is the nucleotide. Wait, no, let's list each component:
• Deoxyribose (sugar): The sugar in DNA is deoxyribose. In the diagram, the sugar is part of the nucleotide and the sugar - phosphate backbone. The label for sugar (deoxyribose) is F? Wait, maybe the correct matches are:
• 1. Deoxyribose (sugar): The sugar is labeled as F? Wait, no, let's check the standard DNA structure labels. Let's go through each:
• 1. Deoxyribose (sugar): In the DNA diagram, the sugar (deoxyribose) is represented by F? Wait, the options: b is F. So 1 matches with b (F).
• 2. Hydrogen bonds: Hydrogen bonds hold the nitrogenous base pairs together. In the diagram, the bonds between base pairs (like A - T, G - C) are hydrogen bonds, labeled as A? Wait, no, the label A is bonds? Wait, the label A is "A bonds" and C is "C bonds". Wait, hydrogen bonds are between base pairs, so maybe A is hydrogen bonds? No, wait, covalent bonds are between sugar and phosphate (covalent) and between nucleotides in the backbone (covalent). Hydrogen bonds are between base pairs. Let's correct:
• 1. Deoxyribose (sugar): The sugar is part of the nucleotide and the backbone. The label for sugar (deoxyribose) is F (option b).
• 2. Hydrogen bonds: Hydrogen bonds are between the nitrogenous base pairs, so the bonds labeled as A? Wait, no, the label C is "C bonds" and A is "A bonds". Wait, maybe hydrogen bonds are labeled as A? No, let's recall:
• Nucleotide: B (the red - circled part is a nucleotide, so 3. Nucleotide matches d (B).
• Phosphate: The phosphate group is part of the nucleotide and the backbone. The label for phosphate is E? Wait, option c is E. So 4. Phosphate matches c (E).
• Nitrogenous base pair: The base pairs (like A - T, G - C) are held by hydrogen bonds. The label for nitrogenous base pair? Wait, the base pairs are the pairs of bases, so maybe D? Option a is D. So 5. Nitrogenous base pair matches a (D).
• Covalent bond: Covalent bonds are between sugar and phosphate (in the backbone) and between nucleotides. The label for covalent bonds is C? Option f is C. So 6. Covalent bond matches f (C).
• Wait, let's start over:
• 1. Deoxyribose (sugar): In DNA, the sugar is deoxyribose. In the diagram, the sugar is labeled as F (option b). So 1 - b.
• 2. Hydrogen bonds: Hydrogen bonds hold the base pairs together. In the diagram, the bonds between base pairs (like A - T, G - C) are hydrogen bonds, labeled as A? Wait, the label A is "A bonds". So 2 - e (A).
• 3. Nucleotide: A nucleotide consists of sugar, phosphate, and nitrogenous base. The red - circled part (B) is a nucleotide. So 3 - d (B).
• 4. Phosphate: The phosphate group is part of the nucleotide and the backbone. The label for phosphate is E (option c). So 4 - c (E).
• 5. Nitrogenous base pair: The base pairs (e.g., A - T, G - C) are the pairs of nitrogenous bases. The label for the base pair is D (option a). So 5 - a (D).
• 6. Covalent bond: Covalent bonds are between sugar and phosphate (in the backbone) and between nucleotides. The label for covalent bonds is C (option f). So 6 - f (C).
• Wait, but let's check again:
• Deoxyribose (sugar): The sugar is part of the nucleotide and the sugar - phosphate backbone. The label F is the sugar? So 1. Deoxyribose (sugar) - b (F).
• Hydrogen bonds: The bonds between base pairs (A - T, G - C) are hydrogen bonds, labeled as A (option e). So 2. Hydrogen bonds - e (A).
