- QUESTION 19 Match the cellular junction with its characteristic (side of cell, cellular role, intracellular connection or transmembrane protein) tight junctions focal adhesions desomsomes gap junctions A. integrins link the actin-myosin stress fibers to the extracellular matrix B. connexons form pores between cells in an epithelial sheet or tube C. link the intermediate filaments of neighboring cells using homophilic cadherin-cadherin binding D. occludins bind to occludins and prohibit the diffusion of membrane proteins from the baso-lateral surface to the apical surface of epithelial cellsQUESTION 34 Dynosaur inhibits the attachment of the microtubule motor protein dynein to microtubules. What will happen to the mitotic spindle positioning and chromosome segregation if Dynosaur is added at the start of prophase and present through the end of cytokinesis? Mitotic spindle positioning and chromosome segregation will proceed normally. The mitotic spindle would no longer be anchored to the plasma membrane and chromosomes might not be equally distributed between the daughter cells following anaphase. The centrosomes will be pulled more strongly towards the plasma membrane and chromosome segregation would be unaffected. The mitotic spindle would disintegrate, and chromosomes will become randomly positioned all throughout the dividing cell.Question 23 of 25 Among the given statements, which ones describe the lysosomes? Select the correct response(s): They bud off from the trans face of the rough endoplasmic reticulum. They bud off from the trans face of the Golgi apparatus. They contain enzymes that are activated at physiologic pH. They bud off from the cis face of the Golgi apparatus. They contain enzymes that are activated above the physiologic pH. They contain enzymes that are activated below the physiologic pH. They contain enzymes that are activated below or above the physiologic pH. They bud off from the cis face of the rough endoplasmic reticulum. 23

Specifically, O gene-poor regions of thromosomes are located outside the nucleus, whereas gene-rich regions of chromosomes are located inside the nucleus O even-numbered chromosomes are located in the interior of the nucleus, whereas odd-numbered chromosomes are located peripherall O each chromosome appears to occupy a discrete domain O arge chromosomes are more likely to be located in the center of the nucleusQUESTION 6 Which of the following is FALSE about mitotic cell division and mitosis? O A. Mitotic cell division is 6 stages: Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis while mitosis is 4 stages: Prophase, Metaphase, Anaphase, Telophase. O B. The terms mitotic cell division and mitosis are the same and they can be used interchangeably to refer to cells dividing to make more cells. O C.A mitotic cell division includes mitosis and mitosis is part of a mitotic cell division. O D.
