Another example: the HOX proteins made by the fruit fly will help guide its development to make sure its mandibles, antennae, thorax and abdomen all grow in the right order. But because HOX genes are conserved across so many species, you can remove one of them in fruit flies and replace it with a chicken HOX gene and the fly will develop just fine. Surprisingly enough, the outcome of this real-world experiment had nothing in common with the little-known David Cronenberg sequel, “The Fly 3: Chicken Little’s Terrible, Horrible. No Good, Very Bad Day. kids movie In short, there is no such thing as a fly gene, a tomato gene , or a human gene. Just like you could use a yellow LEGO to make Bowser , you could use that same yellow LEGO to make Pikachu 3. You don’t have the “gene for” Huntingtons disease; it’s a mutation. On so many TV shows, you hear characters sighing with relief as they learn they don’t have “the gene for” this and that disease. We all have the Huntington gene, and it happens to have a repeat of three letters, CAG, over and over again. People with Huntington’s disease have a longer stretch of this repeat, as if someone was copy/pasting the repeat and dozed off for a few seconds while h itting “Control - v” .

Malka A-R A gene s purpose is not to cause disease. The gene codes for a protein that has a specific job to do inside your body. For instance, the gene associated with Duchenne muscular dystrophy codes for a protein that normally connects a muscle fiber to its surroundings. When is mutated, the protein can’t do its job, and that’s what causes the disease. 4. Its often more complicated than just 1 gene = 1 disease. In the case of Huntington’s and Duchenne’s muscular dystrophy just one singe gene needs to be mutated for the disease to occur. However, this is not the case for all diseases it can be a lot more complicated than that (Jonathan Jarry throws shade at Taylor Swift) o Asthma: caused by mutations in more than one gene. o Cancer: While there are single mutations that predispose you to developing certain forms of cancer, we know that cancer is an accumulation of many mutations in many different genes. Some of these mutations are known as driver mutations: they are needed to occur to drive the cancer forward. On average, breast cancer needs 4 of these mutations, whereas colon cancer needs 11. Even simple traits like hair an eye colour are far from the one gene, one trait rule. o Hair: a shitload of genes involved in creating the particular shade of hair colour In short, although some physical traits and disease are cause by one mutation in one gene, many are caused by a shared responsibility of many variations in many genes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
