Final answer:
The first 10 amino acid residues of the SOD1 protein using 1-letter abbreviations are M-A-Q-R-A-L-A-Y-I-F-Q.
Step-by-step explanation:
The first 10 amino acid residues of the SOD1 protein, using the 1-letter amino acid abbreviations, are: M-A-Q-R-A-L-A-Y-I-F-Q.
Each letter represents an amino acid. These amino acids are arranged in a specific sequence to form the primary structure of the SOD1 protein. The primary structure refers to the linear sequence of amino acids from the N-terminus to the C-terminus of a protein.
