MCQ

Question

Sub-cellular fractionation-based assays have been used to identify various organelles in the mammalian cells. In order to characterize such organelles in a living mammalian cell, which of the following microscopy-based method would be the most accurate?

Options

Choose one · Correct answer highlighted

use of fluorescent probes specific for organelles. use of organelle specific fluorescent probes followed by microinjection of fluorescent antibodies against organelle specific protein . Correct use of fluorescent probes in permeabilized cells. use of organelle specific fluorescent probes followed by cryoelectron microscopy

Explanation

sub-cellular fractionation-based assays have been used to operates via use of organelle specific fluorescent probes followed by mic represents established outcome. functional assays validates option B. Other options propose substrate or regulatory direction, inconsistent with published kinetics and mutant phenotypes.
