D
Golgi apparatus
Verified step by step guidance1
Recall that in eukaryotic cells, genomic DNA is stored in a specific organelle that protects and organizes the genetic material.
Understand that the nucleus is a membrane-bound organelle that contains most of the cell's genetic material in the form of DNA.
Recognize that other organelles like the rough endoplasmic reticulum, lysosome, and Golgi apparatus have different functions such as protein synthesis, digestion, and protein modification, respectively, and do not contain genomic DNA.
Conclude that the primary location of genomic DNA in a typical eukaryotic cell is the nucleus.
Therefore, the correct answer is the nucleus.
