Question

Choose the incorrect pair from the following.

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

Answer 1

Answer: (B)

Nucleus contain DNA and chromosomes, but in also contains other components. For example, the nucleus contains the nucleolus, a mess of strands of nucleic acid. Also, the nucleus contains RNA, which convey the DNA's messages to the cell.

Option B is the incorrect pair as protein synthesis takes place in the endoplasmic reticulum.

Respiration is a process that needs energy and since the source of energy is the mitochondria, it occurs in the mitochondria.

The cytoskeleton of eukaryotes (including human and all animals cells) has three major components: microfilaments composed of the protein actin and microtubules composed of the protein tubulin are present in all prokaryotic cells.

Therefore, the correct answer is option B.
