Question

a student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. why would this procedure fail to produce a prokaryotic cell?
the cell would lack genetic information.
the cell would lack the structure that is needed to produce energy.
the cell would lack the structure that is needed to protect the cells organelles.
the cell would lack control over materials that move into and out of the cell.

Explanation:

Prokaryotic cells have genetic information in the form of a circular DNA molecule in the cytoplasm. Eukaryotic cells have their genetic information mainly in the nucleus. Removing the nucleus from a eukaryotic cell would leave it without its main store of genetic information, which is a key characteristic of cells. Energy - production structures (like mitochondria in eukaryotes and cell membrane - related processes in prokaryotes) are not directly related to the nucleus removal in terms of creating a prokaryotic cell. The structure to protect organelles (cell membrane and cell wall in some cases) is also not related to the nucleus. Control over materials moving in and out is mainly the function of the cell membrane, not the nucleus.

Answer:

The cell would lack genetic information.
