To find: “During mitosis, the nuclear envelope breaks down and intranuclear proteins completely intermix with cytosolic proteins”. Whether this is consistent with the evolutionary scheme proposed about the ancient eukaryotic cell.
Concept introduction:
Cytosol also known as cytoplasmic matrix or intracellular fluid is a part of the cytoplasm which is inside the cell membrane. During the mitosis process in the eukaryotic cells, the protein components present inside the nucleus and the cytosolic contents will mix with each other. According to the proposed evolutionary scheme of eukaryotic cell, the nucleus surrounded by nuclear envelope is a sub-compartment of the cytosol and only through nuclear pores, the cytosol can access the nucleus.
