The sequence of amino acids in a protein is determined by DNA. In a protein that is present in all species, the amino acid sequence will be different. Once a protein has been chosen, the amino acid sequence of that protein in different species are compared. More similarities, or fewer differences, indicate that two species are closely related. (sorry if im wrong!)
I am confident that the answer should be.....<span>A protein acts as a pump and moves calcium ions from an area of low concentration to an area of high concentration.
