Apurified protein is working well in a laboratory test. the researcher adds a new chemical to the mixture in the test tube and notices that the protein stops working. upon further investigation, the researcher is able to determine that the protein still has its normal sequence of amino acids. the protein must have had a change in its

Shape

Explanation:

Under the given scenario , during the process of purification of protein , the protein tends to change its shape and thus the similar incidence took place in this particular case. The purification of protein is referred to as the a series of process that are intended to isolate the proteins from the complex mixture, i.e. usually tissues, cells or a whole organisms.
