What advantage do images produced by freeze-fracturing and freeze-etching have over images generated with freeze-fracturing alone?
A)The images with freeze-fracture-freeze-etch are three-dimensional.
B)The images with freeze-fracture-freeze-etch are in color.
C)The images with freeze-fracture-freeze-etch reveal both the external and the internal surfaces of the cell membrane.
D)The images with freeze-fracture-freeze-etch reveal only the external surface of the cell membrane.
E)The images with freeze-fracture-freeze-etch reveal only the internal surface of the cell membrane.

Question

Freeze-fracturing alone produces images of the internal surfaces of a sample, while freeze-etching is necessary to reveal the external surfaces. Freeze-fracture-freeze-etch imaging allows for both the internal and external surfaces of the cell membrane to be revealed, providing more comprehensive information about the sample. The technique does not, however, provide three-dimensional or color images.
