An 8-mer oligopeptide has the following amino acids: A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i. e. ABCDEFGH.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
