You need to determine the sequence of a linear decapeptide. The following experiments have been performed:
1. Edman degradation generates 10 amino acids: Q, E, M, R, K, C, F, P, Y, A.
2. Cyanogen bromide (CNBr) cleavage gives two pentapeptides (5 aa’s).
3. Trypsin cleavage gives two tripeptides (AMR and QFK), and a tetrapeptide.
4. Chymotrypsin cleavage gives a dipeptide QF, a single amino acid, and a heptapeptide (7).
5. The C-terminal residue is identified as Cys using carboxypeptidase C, which removes amino acids from the C-terminal end of a polypeptide.
Give two possible sequences for the decapeptide, using aa three-letter codes.

Astudent sees several ants walking up a wall following the exact same trail that an ant took earlier. she wants to apply the scientific method to determine how the ants detected the trail. which of these steps would come first in her application of the scientific method? perform an experiment by cleaning the scent away from part of the trail. draw a conclusion that the ants follow a scent trail. make a prediction about what the ants will do after she cleans away part of the trail. hypothesize that the ants are following a scent trail that the first ant left.
