Summary Introduction
To analyze:
Genetic engineering project that includes nitrogen fixation.
Introduction:
Genetic engineering is the process in which the characteristics of an organism are modified by changing its genetic material. The main goal of this process is to add one or more traits in the organism that are not already found. This technique has been used in different fields, such as animal husbandry, medicine, and agriculture.

(So to get you started, notice the class 1 mutants—and there is only mutant in this class, which is mutant #5—won’t grow on minimal medium, but will grow if you give it substance Z. However, giving it substances, p, w, x, or y won’t help. This means that the gene that is mutated lies on the pathway in a place that the Z substances is to its right and all the other substances are to its left. The easiest next one to look at is the line with 2 pluses, and then the line with 3 pluses, and then the line with 4 pluses).arrow_forward
