Using the information in problem 3, make another plot showing how DX and DP (rates of production of cells andproduct) vary with D (on the same graph), covering the same range of dilution rates in problem 3.5. Genetics & Gene ControlA. Explain the difference between a DNA strand, a chromosome and a gene.B. Would a cell with a deletion or a point mutation be more likely to revert back to the original phenotype?Why?C. Define feedback repression. On a basic level, how does this work in a cell?
