Which one of the following statements is worng ?

Options

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

Answer

To determine which statement is wrong, let's analyze each option provided in the question:

1. **Cellulose is a polysaccharide.**
- Cellulose is indeed a polysaccharide made up of long chains of glucose molecules linked together. It is a major component of plant cell walls. This statement is **true**.

2. **Uracil is a pyrimidine.**
- Uracil is one of the nitrogenous bases found in RNA and is classified as a pyrimidine. Pyrimidines include uracil, cytosine, and thymine. This statement is **true**.

3. **Glycine is a sulfur-containing amino acid.**
- Glycine is the simplest amino acid with the formula NH2CH2COOH. It does not contain sulfur in its structure. Therefore, this statement is **false**.

4. **Sucrose is a disaccharide.**
- Sucrose is a disaccharide composed of glucose and fructose linked by a glycosidic bond. This statement is **true**.

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

### Step-by-Step Solution:
1. **Identify the statements provided.**
- List the four statements given in the question.

2. **Evaluate each statement for accuracy.**
- Check the definition and composition of cellulose, uracil, glycine, and sucrose.

3. **Determine the truth value of each statement.**
- Confirm that cellulose, uracil, and sucrose are correctly described.
- Identify that glycine does not contain sulfur.

4. **Conclude which statement is incorrect.**
- State that the wrong statement is about glycine being a sulfur-containing amino acid.
