Question

To localize proteins and other types of molecules in cells:

A. Fluorescence microscopy is often used.

B. Labelled antibodies can be used to localize a type of protein.

C. Labelled synthetic molecules that recognize a specific type of biomolecule (e.g. DNA) can be used.

D. All of the above (ABC).

E. None of the above

Answer 1

Option D

To determine the production of a specific by molecule inside a cell, we need to label it either with the help of a fluorescent dye or a radioactive element. Both fluorescent dye and radioactive element will be fused with the biomolecules if we see it under an appropriate instrument, fluorescent microscope if fluorescent dye is used and UV lamp if a radioactive element is used, then we will see brightened appearance of that biomolecule with which fluorescent dye or radioactive element has been fused.
