The identity of a protein has relation with its amino acid sequence. This sequence is determined by the nucleotide sequence of the DNA of the gene transcribed to RNA and translated into amino acids. Protein identity determines its structure and function. The concentration of a protein refers to the percentage of protein that exists in a given solution. One way to quantify the concentration is with a spectrophotometer calculating the absorbance of the protein.
