Final answer:
Eukaryotic cells have complex genes compared to prokaryotic cells due to their larger genomes, more genes, alternative splicing, and chromatin packaging.
Step-by-step explanation:
Eukaryotic cells have complex genes compared to prokaryotic cells. Prokaryotic cells are single-celled organisms with a simpler structure, such as bacteria, while eukaryotic cells are multicellular organisms with more complexity, like plants and animals. Eukaryotic cells have a nucleus that contains DNA, which controls cellular function. Gene regulation in eukaryotes is more complex due to their larger genomes, more genes, alternative splicing, and chromatin packaging.
