Normal DNA sequence and Normal ospins go to nom color blind or normal vision the rest go to the the one that causes colorblind
The answer possibly could be a drought but I’m not 100%
Raising the temperature will denature an enzyme so that it is no longer functional. Lowering the temperature will reduce the rate of the reaction so low as to make it seem non-functional. Altering the pH above or below its optimum pH will also reduce the enzyme's activity, and at extremes the enzyme may be permanently denatured.
