Question

number the carbon atoms in the deoxyribose sugar of dna. drag the labels to their appropriate locations in the diagram. 2 - deoxyribose

Explanation:

Step1: Identify carbon - 1

The carbon atom attached to the nitrogen - containing base (not shown in this partial structure but in full DNA structure) is carbon - 1. In the given deoxyribose structure, it is the carbon on the right - hand side of the ring oxygen.

Step2: Identify carbon - 2

The carbon with the hydrogen instead of a hydroxyl group (in deoxyribose compared to ribose) is carbon - 2. It is next to carbon - 1 in the ring.

Step3: Identify carbon - 3

The carbon with the hydroxyl group on the ring, adjacent to carbon - 2, is carbon - 3.

Step4: Identify carbon - 4

The carbon that connects the ring to the $HOCH_2$ group is carbon - 4.

Step5: Identify carbon - 5

The carbon in the $HOCH_2$ group is carbon - 5.

Starting from the carbon on the right - hand side of the ring oxygen and moving clock - wise around the ring and then to the $HOCH_2$ group:

1. The carbon on the right - hand side of the ring oxygen is carbon - 1.
2. The carbon with the hydrogen instead of a hydroxyl group is carbon - 2.
3. The carbon with the hydroxyl group on the ring is carbon - 3.
4. The carbon that connects the ring to the $HOCH_2$ group is carbon - 4.
5. The carbon in the $HOCH_2$ group is carbon - 5.

Answer:

Starting from the carbon on the right - hand side of the ring oxygen and moving clock - wise around the ring and then to the $HOCH_2$ group: 1, 2, 3, 4, 5.
