REF: p. 2 • A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information be contained? • Mitochondria • Ribosome • Nucleolus • Nucleu... s Cytoplasm ANS: C The region of the cell that contains genetic material, including a large amount of ribonucleic acid, most of the DNA, and DNA-binding proteins, is the nucleolus, which is located within the cell’s nucleus. Mitochondria is associated with cellular respiration, while ribosomes are involved with protein manufacturing. Cytoplasm is a fluid filling that is a component of the cell. REF: p. 2 • Which of the following can remove proteins attached to the cell’s bilayer by dissolving the layer itself? • Peripheral membrane proteins • Integral membrane proteins • Glycoproteins • Cell adhesion molecules ANS: B Proteins directly attached to the membrane bilayer can be removed by the action of integral membrane proteins that dissolve the bilayer. Peripheral membrane proteins reside at the surface while cell adhesion molecules are on the outside of the membrane. Glycoprotein marks cells and does not float. REF: p. 7 • Which of the following can bind to plasma membrane receptors? • Oxygen • Ribosomes • Amphipathic lipids • Ligands ANS: D Ligands are the only specific molecules that can bind with receptors on the cell [Show More]
