3. You want to characterize the effects of four upstream regulatory elements on the expression of a bacterial gene. You collected data from four strains of bacteria by measuring gene expression. Based on the genome sequences of the strains, you know what combination of regulatory elements appear in each strain. The data are summarized in the following table (25 pts). element 1 element 2 element 3 element 4 expression yes no yes no 0.63 yes yes no no 1.25 yes yes yes yes 2.78 yes no no yes 1.44 Assuming that each regulatory element acts independently, write a system of linear equations that describes how the gene's expression depends on the presence or absence of the regulatory elements. Let the unknown variables x1, x2, x3, and x4 represent the contribution each regulatory element makes toward gene expression. Solve your linear system to find the contributions of each element.
