The question was incomplete but I managed to found it some other source. Please find that in the attached picture.
Answer:
<u>The earliest step: </u>
Formation of amino-acid building blocks
<u>The second step: </u>
Joining amino-acids into a polymer like beads on a string (this order is the 'primary structure')
<u>The third step:</u>
The first part of the protein folds due to side-chain and backbone interactions
<u>The fourth step</u>:
The final protein tertiary structure is completed with the addition and folding of the last parts of the protein.
<u>The last of these steps:</u>
The enzymatic function is possible due to the completed tertiary structure creating an 'active site' region of the protein.
