Guida verificata passo dopo passo1
Understand the structure and function of the nucleus in eukaryotic cells: The nucleus is the organelle that houses the cell's genetic material.
Recall that human cheek cells are eukaryotic cells, so their nucleus contains the cell's DNA organized into chromosomes.
Identify that ribosomes attached to rough endoplasmic reticulum are found outside the nucleus, associated with the ER membrane, not inside the nucleus.
Recognize that ATP-producing enzymes are located in the inner mitochondrial membrane, which is part of mitochondria, not the nucleus.
Know that hydrolytic enzymes used for intracellular digestion are found in lysosomes, not inside the nucleus.
