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, we will analyze each of the provided statements one by one.

### Step 1: Analyze the first statement
**Statement:** Sucrose is a disaccharide.
**Explanation:** Disaccharides are carbohydrates formed from two monosaccharides. Sucrose is composed of glucose and fructose, which confirms that it is indeed a disaccharide.
**Conclusion:** This statement is **correct**.

### Step 2: Analyze the second statement
**Statement:** Cellulose is a polysaccharide.
**Explanation:** Polysaccharides are carbohydrates made up of many monosaccharides. Cellulose is a structural component of the plant cell wall and is composed of many glucose units linked together.
**Conclusion:** This statement is **correct**.

### Step 3: Analyze the third statement
**Statement:** Uracil is a pyrimidine.
**Explanation:** In the context of nucleic acids, pyrimidines are nitrogenous bases that include cytosine, thymine, and uracil. Since uracil is found in RNA and is not present in DNA (where thymine is), it is classified as a pyrimidine.
**Conclusion:** This statement is **correct**.

### Step 4: Analyze the fourth statement
**Statement:** Glycine is a sulfur-containing amino acid.
**Explanation:** Glycine is one of the simplest amino acids and does not contain sulfur in its structure. Sulfur-containing amino acids include cysteine and methionine. Therefore, this statement is incorrect.
**Conclusion:** This statement is **wrong**.

### Final Conclusion
The statement that is wrong is: **"Glycine is a sulfur-containing amino acid."**
