Which of the following accurately describes a step in GTP-driven nuclear transport? GTP hydrolysis powers a membrane-bound transporter protein. GTP-bound cargo interacts specifically with the protein fibrils of the pore. Binding of Ran-GTP to the receptor releases the cargo protein. Ran-GDP escorts the nuclear receptor back to the cytosol.

Which of the following statements about the role of the COPI or COPII proteins in vesicular transport is CORRECT? They pinch and fuse the membrane to allow separation of the vesicle from the rest of the membrane of the donor compartment. They increase the curvature of the membrane and form the vesicle from the donor compartment. They bind to the membrane of the target organelle/compartment to ensure delivery specificity. They regulate the fusion of the vesicle membrane with its target...

Immunocytochemistry is the method of visualization of proteins in cells with the use of antibody that recognize specific molecules. Recently the visualization of these antibody-bound molecules is realized with the imaging of fluorescently-labeled antibodies against these receptors. Which type of microscopy would be used for this study? 0. Confocal microscopy O. Phase-contrast microscopy O. Differential interference contrast microscopy Electron phase-contrast microscopy You are working on a project that involves an imaging of rough endoplasmic reticulum shown here.
