Answer

To determine which statement is wrong, we will analyze each of the four statements provided:

1. **Sucrose is a disaccharide.**
- Sucrose is indeed a disaccharide composed of two monosaccharides: glucose and fructose. Therefore, this statement is **true**.

2. **Cellulose is a polysaccharide.**
- Cellulose is a polysaccharide made up of many glucose monomers linked together. Thus, this statement is also **true**.

3. **Uracil is a pyrimidine.**
- Uracil is one of the nitrogenous bases found in RNA and is classified as a pyrimidine. Therefore, this statement is **true**.

4. **Glycine is a sulfur-containing amino acid.**
- Glycine is an amino acid, but it does not contain sulfur. The sulfur-containing amino acids are methionine and cysteine. Hence, this statement is **false**.

Based on the analysis, the wrong statement is:
