How do you show the difference between these two amino acids?

Question

I first compared the amino acid sequences with MEGA, and then imported them into genedoc. The results showed that there was no difference between L and M, and the common sequence showed the number 6, both with black background. Is it because the physical and chemical properties of the amino acids were similar that the two amino acids were not consistent? How do you show the difference between these two amino acids?

Answer 1

It is likely that the two amino acids have similar physical and chemical properties, which is why they are not showing up as different in GeneDoc.
