It’s amazing to me that with the number of possibilities for genetic defects and disorders that so many people’s genes actually work. Given that it only takes one small change in one tiny base pair for a mutation to occur, and there are so many different reactions that have to happen perfectly, it’s incredible we work at all. I’m really liking learning about all of this. It just reinforces the idea that everything is so random—it seems like so much luck, and how in the world did it all work out? I especially enjoyed the lab on Thursday—but I wonder what it means that when you’re distracted your reaction time is slower. Does it mean you’re using more neurons for something else and so they’re divided and can’t decide what to do?
