I think the translation might be at fault, it should be “with many substituted amino acids” for it to make sense in my opinion

Ohhh so basically a single base change can’t produce more amino acids that are substituted?

A single base change can substitute just the one amino acid it codes for, not any of the others in the peptide, so I think yes

Yeah I thought so too, thank you for clearing that up Juliette!! You’re a great help:))
