Which one will be the molecular formula for the sugar involved in making RNA ?

Options

A. `C_5H_(10)O_5`
B. `C_5H_(12)O_5`
C. `C_5H_(10)O_6`
D. `C_(12)H_(22)O_11`

Answer

To determine the molecular formula for the sugar involved in making RNA, we can follow these steps:

### Step 1: Understand the Components of RNA
RNA, or ribonucleic acid, is a type of nucleic acid that plays a crucial role in coding, decoding, regulation, and expression of genes. It is composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

**Hint:** Recall that RNA is different from DNA, particularly in the type of sugar it contains.

### Step 2: Identify the Sugar in RNA
The sugar present in RNA is ribose. Ribose is a five-carbon sugar (pentose) that is essential for the structure of RNA.

**Hint:** Remember that ribose has a specific number of carbon, hydrogen, and oxygen atoms.

### Step 3: Determine the Molecular Formula of Ribose
The molecular formula for ribose is C5H10O5. This indicates that ribose has 5 carbon atoms, 10 hydrogen atoms, and 5 oxygen atoms.

**Hint:** You can derive the formula by counting the atoms in the ribose structure.

### Step 4: Analyze the Options Given
In the question, we need to evaluate the options provided for the molecular formula. The correct molecular formula for the sugar in RNA (ribose) is C5H10O5.

**Hint:** Compare the provided options to identify which one matches C5H10O5.

### Step 5: Conclusion
After analyzing the options, we conclude that the correct molecular formula for the sugar involved in making RNA is C5H10O5.

**Final Answer:** C5H10O5
