Homework Answers
Answer : Option (3) GTP and ATP donate a phosphate to another target
Explanation : GTP stands for Guanosine Tri Phosphate and ATP stands for Adenosine Tri Phosphate. Both of them donate phosphate group to another target and become GDP and ADP respectively. With subsequent donation of phosphate group, GMP and AMP are formed.

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.
