A Type I Membrane Protein Has Which of the Following

Question

A Type I membrane protein has which of the following structures?
A) Both the C-terminus and the N-terminus face the inside of the virion.
B) It passes through the viral envelope multiple times.
C) The N-terminus faces outside the virion and the C-terminus faces inside the virion.
D) The N-terminus faces inside the virion and the C-terminus faces outside the virion.
E) The protein lacks a transmembrane domain and is secreted from the infected cell.

Accepted Answer

A Type I membrane protein typically has a transmembrane domain that anchors it to the viral envelope, with the N-terminus facing outside the virion and the C-terminus facing inside the virion. This orientation allows the protein to interact with the host cell and play a role in viral entry or infection.
