A researcher is assessing the expression of a certain protein in cells. This protein appears as a "web" in the cytoplasm of cells. The protein is likely a component of:
A)the cytoskeleton.
B)cell junctions.
C)the extracellular matrix.
D)of the basal lamina.
E)All of these choices are correct.

Question

Quizplus · Accepted Answer

The cytoskeleton is a network of protein filaments and tubules that provide structure and support to cells. The fact that the protein appears as a "web" in the cytoplasm of cells suggests that it is part of the cytoskeleton. Cell junctions, the extracellular matrix, and the basal lamina are all distinct structures that are not typically associated with a "web-like" protein structure in the cytoplasm. Therefore, the best choice is A, the cytoskeleton.
