Your colleague wants to examine receptor-mediated endocytosis in a mutant cell line. Specifically, they want to obtain an image that is a “slice” through a cell, showing both the inside and the outside of the cell at the same time. What type of imaging technique should they use?

Glycosylation is

Proteins transported from the endoplasmic reticulum to the Golgi apparatus are carried in vesicles surrounded by:

A polypeptide with a stop-transfer sequence will be a:

What is co-translational folding?

A solute that is moved across a membrane from an area where it is highly concentrated to an area where it is less concentrated is moving:

TRUE or FALSE: Ionic bonds become weaker (and therefore easier to break) in water. 

TRUE or FALSE: The ubiquitin pathway is only used by the cell to degrade proteins. 

What is a TRUE statement about O-linked glycosylation?

TRUE or FALSE: The only time that chromatin is densely packed is when it is packaged up in chromosomes (X shapes).
