Find the x-intercept of the function y=0.2x+0.55 Lets think about mutations in the context of selection and evolution. Normally, random mutations are very rare, but this process can be accelerated by using DNA damaging agents. Imagine you are working with yeast. Normally, high levels of salt kill yeast. However, you are conducting a random genetic screen to find salt-tolerant mutants. You use a DNA damaging agent (like EMS, or UV light) to damage the yeast DNA, then look for growth on plates with salt.a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine). Following the 2007-2009 financial crisis, many people feared that Greece might leave the euro and resume using the drachma.
