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?

A
The cell would lack genetic information.
B
The cell would lack genetic information.
C
The cell would lack the structure that is needed to produce energy.
D
The cell would lack the structure that is needed to produce energy.
E
The cell would lack the structure that is needed to protect the cell’s organelles.
F
The cell would lack the structure that is needed to protect the cell’s organelles.
G
The cell would lack control over materials that move into and out of the cell.
H
The cell would lack control over materials that move into and out of the cell.
