Which of the Following is Unlikely to Be a Characteristic

Question

Which of the following is unlikely to be a characteristic of a membrane protein?
A) Largely hydrophobic transmembrane segments
B) α-helical membrane-spanning motifs.
C) Covalently attached lipid moities
D) Symmetric orientation across the membrane
E) β-sheet membrane-spanning motifs

Accepted Answer

Membrane proteins can have asymmetrical orientation across the membrane, as they may have different functional domains on either side of the membrane. Choices A, B, C, and E are all potential characteristics of membrane proteins.
