Answer the following question given this paragraph: 

After a polypeptide chain is synthesized, it may undergo additional processes. For example, it may assume a folded shape due to interactions among its amino acids. It may also bind with other polypeptides or with different types of molecules, such as lipids or carbohydrates. Many proteins travel to the Golgi apparatus to be modified for the specific job they will do. You can see how this occurs by watching the animation at this link: http://vcell. ndsu. edu/animations/proteinmodification/movie-flash. htm .


Q: What part of a cell do proteins travel to to be modified for the specific job they will do?

 Choices:

- plasma membrane

- lysosome

- nucleus

- golgi apparatus

A:
golgi apparatus
