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