Web8 jun. 2024 · As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. A few types of fungi have structures comparable to bacterial plasmids (loops of DNA). Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus. WebIntroduction. The nucleus is a membrane-bound organelle which contains genetic material (DNA) in all eukaryotic organisms. Therefore, it functions to keep the integrity of their cell by easing transcription and replication procedures.
