A mutation that disrupts the ability of an animal cell to add polysaccharide modifications to proteins would most likely cause defects in which of the following structural elements?
A) extracellular matrix
B) intermediate filaments
C) microfilaments
D) microtubules

Question

Quizplus · Accepted Answer

The extracellular matrix (ECM) is rich in glycoproteins, which are proteins modified with polysaccharides (sugar chains). A mutation that disrupts polysaccharide modifications would directly affect the structure and function of the ECM, as these modifications are crucial for the proper organization, strength, and signaling functions of the ECM.
