|
How is the primary level structure created in protein? |
Dehydration synthesis between amino acids. |
|
|
How many structures does a functional protein have? |
3 or 3 level structure |
|
|
What is the secondary structure of a protein? |
Beta pleated sheets and alpha helix. |
|
|
Why is the shape of the protein important? |
Function of protein changes with shape. |
|
|
What is the function of nucleic acids? |
Serves as information storage, transfer molecule and energy transfer. |
|
|
What can nucleic acids be build from? |
2 types of monomers ribose and deoxyribose. |
