Which of the following statements best describes the function of the nuclear pore complex found in eukaryotic cells? It synthesizes the proteins required to copy DNA and make mRNA. It regulates the movement of proteins and RNAs into and out of the nucleus. It synthesizes secreted proteins. It assembles ribosomes from raw materials that are synthesized in the nucleus.

Which of the following nuclear structures is NOT correctly matched with its function? a. The nucleolus - site of rRNA synthesis b. Nuclear pores-allow passage of molecules into and out of the nucleus c. Nuclear envelope-separates the contents of the nucleus from the cytoplasm d. Nuclear lamina- produces ribosomes
Cell Structure
Eukaryotic Cells Are Highly Compartmentalized
Which of these actions occur(s) commonly at a nuclear pore complex? Choose one or more: Nuclear laminins are packaged to be exported out of the cell. Subunits of ribosomes are exported from the nucleus into the cytosol. Fully folded proteins, with a nuclear localization signal, are imported into the nucleus. Small water-soluble molecules are selectively transported into the nucleus. GTP is hydrolyzed to as a source of energy to drive nuclear transport. mRNA molecules are exported to the cytosol.
