Where is genetic information primarily stored within a eukaryotic cell?

• A. In the nucleus
• B. In the mitochondria
• C. In the ribosomes
• D. In the Golgi apparatus

Answer: (A)

Verified step by step guidance

1. Understand the structure of a eukaryotic cell: Eukaryotic cells have various organelles, each with specific functions. The nucleus, mitochondria, ribosomes, and Golgi apparatus are key organelles involved in different cellular processes.
2. Identify the role of the nucleus: The nucleus is the central organelle that houses the cell's genetic material. It contains the DNA, which is organized into chromosomes. This is where the majority of genetic information is stored and managed.
3. Consider the function of mitochondria: Mitochondria are known as the powerhouses of the cell, responsible for energy production through cellular respiration. They also contain a small amount of DNA, but this is not the primary storage site for genetic information.
4. Examine the role of ribosomes: Ribosomes are involved in protein synthesis. They read the genetic information carried by messenger RNA (mRNA) to assemble proteins, but they do not store genetic information themselves.
5. Evaluate the function of the Golgi apparatus: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell. It does not store genetic information.
