The correct Answer is:
To determine what uridine is, we can break down the options provided in the question step by step. **Step 1: Understand the components of uridine.** - Uridine is a nucleoside, which is a compound that consists of a nitrogenous base attached to a sugar molecule. **Step 2: Identify the nitrogenous base in uridine.** - The nitrogenous base in uridine is uracil, which is one of the four bases found in RNA (ribonucleic acid). **Step 3: Identify the sugar component of uridine.** - The sugar component of uridine is ribose, which is a five-carbon sugar that is part of the structure of RNA. **Step 4: Analyze the options provided.** - The options provided are: 1. Nitrogenous base. 2. Nitrogenous base plus sugar. 3. Nitrogenous base plus phosphate. 4. Nitrogenous base plus sugar plus phosphate. **Step 5: Determine the correct answer.** - Since uridine consists of a nitrogenous base (uracil) and a sugar (ribose), the correct answer is option 2: Nitrogenous base plus sugar. **Final Answer:** Uridine is a nitrogenous base plus sugar. ---
