Please answer and explain. Thank you.

1) What is the tertiary structure of a protein and what causes it to form?

2) List the specific types of interaction that hold together the tertiary structure of a protein.

3) For each type of interaction listed above, identify amino acids that could form that type of interaction between ther R groups and draw those interaction below.
