Which of the following match is correct?

Options

A. DNA `rarr beta`-D- deoxyribose
B. DNA `rarr beta` -1-deoxyribose
C. RNA `rarr beta`-D- ribose
D. RNA `rarr beta`-D-deoxyribose

Answer

To determine which of the following matches is correct regarding the sugars present in DNA and RNA, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of DNA**:
- DNA stands for Deoxyribonucleic Acid.
- The sugar present in DNA is **deoxyribose**.
- Deoxyribose is a five-carbon sugar (pentose) that lacks one oxygen atom compared to ribose. Specifically, it is missing an oxygen atom at the 2' carbon position.

2. **Understand the Structure of RNA**:
- RNA stands for Ribonucleic Acid.
- The sugar present in RNA is **ribose**.
- Ribose is also a five-carbon sugar, but it has a hydroxyl group (-OH) at the 2' carbon position.

3. **Compare the Sugars**:
- In DNA (deoxyribose), the structure can be summarized as:
- 1' carbon: attached to the nitrogenous base
- 2' carbon: has a hydrogen atom (H)
- 3' carbon: has a hydroxyl group (OH)
- 4' carbon: part of the ring structure
- 5' carbon: attached to the phosphate group
- In RNA (ribose), the structure can be summarized as:
- 1' carbon: attached to the nitrogenous base
- 2' carbon: has a hydroxyl group (OH)
- 3' carbon: has a hydroxyl group (OH)
- 4' carbon: part of the ring structure
- 5' carbon: attached to the phosphate group

4. **Identify the Correct Match**:
- The correct match is that DNA contains **deoxyribose** and RNA contains **ribose**.
- Therefore, if the options provided include statements about DNA containing deoxyribose and RNA containing ribose, that would be the correct match.

### Conclusion:
The correct match is that DNA contains **deoxyribose** and RNA contains **ribose**.
