    Q:

    		 A set of protein sequences are given in the tables below. Rank the proteins in increasing order of their ability to form disulfide bridges (covalent bonds between the R-groups of two cysteine sulfhydryl groups).

    Protein Sequence
    1 Alanine-Cysteine-Leucine-Threonine-Phenylalanine-Glutamine-Glycine-Glycine-Asparagine-Cysteine
    2 Cysteine-Cysteine-Leucine-Threonine-Phenylalanine-Glutamine-Glycine-Glycine-Asparagine-Glycine
    3 Alanine-Gylcine-Leucine-Threonine-Phenylalanine-Glutamine-Glycine-Glycine-Asparagine-Glycine
