Choose the incorrect one pair from the following .

Options

A. Nucleus - RNA
B. Lysosome - Protein Synthesis
C. Mitochondria - Respiration
D. Cytoskeleton - Microtubules

Answer

To solve the question of identifying the incorrect pair from the given options, we will analyze each option one by one:

1. **Option A: Nucleus - RNA**
- The nucleus is indeed associated with RNA. It contains DNA and is the site where transcription occurs, leading to the synthesis of RNA. Therefore, this pair is correct.

2. **Option B: Lysosome - Protein Synthesis**
- Lysosomes are membrane-bound organelles that contain digestive enzymes. Their primary function is to break down waste materials and cellular debris, not to synthesize proteins. Protein synthesis occurs in ribosomes. Therefore, this pair is incorrect.

3. **Option C: Mitochondria - Respiration**
- Mitochondria are known as the powerhouse of the cell and are responsible for cellular respiration, where glucose is oxidized to produce ATP. Thus, this pair is correct.

4. **Option D: Cytoskeleton - Microtubules**
- The cytoskeleton is a structural framework in the cell and is indeed made up of microtubules, along with microfilaments and intermediate filaments. Therefore, this pair is also correct.

After analyzing all the options, we conclude that the incorrect pair is:

**Answer: Option B - Lysosome - Protein Synthesis**
