Proteins that lack a signal sequence are usually ______.
Understand the Problem
The question is asking about what typically happens to proteins that do not have a signal sequence, which relates to their location and function in the cell.
Answer
cytosol
Proteins that lack a signal sequence are usually located in the cytosol.
Answer for screen readers
Proteins that lack a signal sequence are usually located in the cytosol.
More Information
Proteins without signal sequences typically remain in the cytosol, as the signal sequence determines their transport and localization within the cell. The absence of such signals means they are not relocated to other parts of the cell.
Tips
A common mistake is assuming that all proteins have some form of signal sequence that determines localization. Remember that lack of a signal sequence usually means remaining in the cytosol.
