A typical eukaryotic nucleus has to exchange a great deal of protein and nucleic acid material with the surrounding cytosol of the cell. Which choice correctly describes a feature of most nuclei that helps promote this exchange?A. Many nuclei wait until the start of cell division, when the nuclear membrane barriers are removed, for the exchange of many needed items.
B. There are numerous nuclear pores that allow regulated passage of selected items into and out of the nuclear space.
C. Large numbers of vesicles that fuse with and bleb from the nuclear membranes are used in the movement of these items.
D. Many nuclei increase their membrane surface area relative to the nuclear volume by modifying their shape from that of a sphere.
E. The nuclear envelope membranes are selectively permeable and able to permit the passage of the needed items through their lipid phase.
