Answer:
You can come up with several different answers. See my explanation
Step-by-step explanation:
Probably easiest to first figure out which amino acids these are:
Amino Acid 1 is Lysine
Amino Acid 2 is Alanine
Amino Acid 3 is Glycine
To create two different proteins (that have 4 amino acids in each) just make up two different strings of amino acids:
1. Lysine-Alanine-Glycine-Lysine
2. Alanine-Lysine-Glycine-Glycine
3. Glycine-Glycine-Alanine-Lysine
You can just keep going. Even one change to the order will generate a new protein. Just make sure you use all 3 amino acids and make sure the order is different!
