(d) To determine the sequence of the protein

The question was posed to me by my school principal while I was bunking the class.

The query is from Protein Folding in portion Biomolecules and Catalysis of Life Sciences

Answer 1

Correct answer is (a) To determine the amount of protein

To explain: Protein assay is a technique to determine the amount of protein in an unknown solution. It is done by measuring the absorbance at 280nm. Aromatic side chain containing amino acids like tyrosine, tryptophan, and phenylalanine exhibit strong UV light absorbance.
