For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below.  Not all words or phrases will be used; each word or phrase should be used only once. There are several ways that membrane proteins can associate with the cell membrane.  Membrane proteins that extend through the lipid bilayer are called [1] proteins and have [2] regions that are exposed to the interior of the bilayer. Some other proteins are [3] attached to lipid molecules that are inserted in the membrane.  [4] membrane proteins are associated with the membrane through noncovalent interactions with other membrane-bound proteins. In animals, proteins constitute ~ [5] of the total mass of the plasma membrane. Transmembrane proteins that are destined for the plasma membrane are first inserted into the membrane of the [6]. 

After isolating the rough endoplasmic reticulum from the rest of the cytoplasm, you purify the RNAs attached to it.  Indicate whether you expect these RNAs to encode the following types of proteins (Indicate Yes or No for each type of the proteins). proteins to be inserted into the plasma membrane [1] proteins to be delivered to the Golgi apparatus [2] proteins to be imported into the nucleus [3] proteins to be secreted to the extracellular space [4]
