DNA damage can occur from mistakes in DNA replication, chemical reactions, physical bumping of molecules due to thermal collisions, and UV radiation from sunlight. One type of DNA damage known as DNA mismatch, however, is virtually a result of a Mismatch repair proteins can detect the DNA mismatch, remove the incorrectly paired nucleotide, and insert the correct nucleotide in its place, using the as a template. A mistake in detecting which of the two strands contains the incorrect nucleotide can result in amino acid substitutions that may impact key cellular processes. In bacteria, parent strands are , allowing the mismatch repair proteins to detect this difference and then make the change on the unmodified strand.

Remember the equation for GDP that we learned? No? Well good becasue that's not the question so you don't need to remember it. In fact, i'm going to tell you. The equation for GDP is Y = C+I+G+ [X-M]. Now, here's the question. Remember how we said that it kind of makes sense, at least mathematically that if M is greater than X (meaning we import more than we export) GDP will fall. But we also said that this is an equation with the problem of endogeneity. What does this mean? a. It means that the math works and if X>M GDP falls b. It means that each of the variables in the equation affect, and reinforce each other so that if NX<0 (we are an importer) then the other variables will fall c. It means that the variables in the model do not interact with one another. d. It means that each of the variables affects each other and just because we may be an importer doesn't mean that GDP will actually fall. What if by importing we free up more money for consumption to rise in a factor more than imports increase? Then GDP will rise.
