One of the “a” position in sequence # 1 is a hydrophilic amino acid One of the “a” position in sequence #2 is a hydrophilic amino acid One of the “d” position in sequence # 2 is hydrophilic amino acid

  

One of the “a” position in sequence # 1 is a hydrophilic amino acid One of the “a” position in sequence #2 is a hydrophilic amino acid One of the “d” position in sequence # 2 is hydrophilic amino acid The majority of the “a” and “d” positions in both sequences 1 and 2 are aliphatic amino acid residues
