Question

In RNA, which type of sugar is present?

• A. Ribose.
• B. Deoxyribose.
• C. Glucose.
• D. Fructose.

Hint:

Remember, RNA contains ribose, while DNA contains deoxyribose, which lacks the -OH group at the 2' position.

Answer 1

The Correct Option is A

Step 1: Understanding the Question.
RNA (ribonucleic acid) contains a sugar molecule that is crucial for its structure. This sugar is different from the sugar found in DNA.
Step 2: Analyzing the Options.
- (A) Ribose is the sugar present in RNA, and it has a hydroxyl group (-OH) at the 2' carbon.
- (B) Deoxyribose is the sugar found in DNA, where the 2' carbon lacks the hydroxyl group.
- (C) Glucose is not the sugar used in RNA or DNA.
- (D) Fructose is not the sugar in RNA.
Step 3: Conclusion.
The correct answer is (A) Ribose.
