One of the big challenges for a nucleic acid vaccine is actually getting the DNA or RNA to go inside the host cell's membrane. One way to do this is to wrap the nucleic acid up in a little package of macromolecules just like how the golgi body packages things up things we want to export. Based on this description, you would guess that the best thing to package the genetic material would be:

Question Completion:

- a large carbohydrate with partial charges

- a phospholipid

- a nucleic acid carrying

- a negative charge

- a highly polar protein

Based on this description, you would guess that the best thing to package the genetic material would be:

- a phospholipid

Explanation:

Since phospholipids work to provide pathways for various substances across cell membranes, they appear to be the best agents or packages for exporting the genetic material of a nucleic acid vaccine.  As cell membranes, phospholipids can allow selective passage of some substances into and out of the cells, even though they act as barriers to other molecules and ions.
