Which one of the following statements is wrong?

Options

A. Sucrose is a disaccharide.
B. Cellulose is a polysaccharide.
C. Uracil is a pyrimidine.
D. Glycine is a sulphur containing amino acid

Answer

To determine which statement is wrong, let's analyze each statement one by one:

1. **Sucrose is a disaccharide.**
- Sucrose is indeed a disaccharide composed of one glucose molecule and one fructose molecule. This statement is correct.

2. **Cellulose is a polysaccharide.**
- Cellulose is a polysaccharide made up of long chains of glucose units linked together. This statement is also correct.

3. **Uracil is a pyrimidine.**
- Uracil is classified as a pyrimidine base, which is one of the nitrogenous bases found in RNA. This statement is correct as well.

4. **Glycine is a sulfur-containing amino acid.**
- Glycine is the simplest amino acid and has a side chain that consists of a single hydrogen atom (H). It does not contain sulfur. The amino acids that contain sulfur are Methionine and Cysteine. Therefore, this statement is incorrect.

Based on the analysis, the wrong statement is:
**Glycine is a sulfur-containing amino acid.**

### Step-by-Step Solution:
1. Identify the statements provided.
2. Analyze each statement for its accuracy.
- Check if sucrose is a disaccharide.
- Check if cellulose is a polysaccharide.
- Check if uracil is a pyrimidine.
- Check if glycine contains sulfur.
3. Conclude which statement is incorrect based on the analysis.
