September Alpha test Here in Italy most universities have faculties that require you to do a pre-course evaluation(which is named Alpha test). The result that comes out of the evaluation is calculated following this rules: 1,5 points if the answer is correct; 0 points if one didn't answer the question; -0,4 if you answered incorrectly. You have 100 minutes to answer 60 questions, every answer is given based on multiple choices(1 correct question out of 5). The subjects of the exam are many but the main ones are general culture, biology, chemistry and physics. I'm currently studying biology( I applied for physioterapy) and I have to say that discovering how life works at a biomolecular level it's just astonishing. One thread that really got me lighten up is genetic. Basically a cell is able to copy DNA into another molecule named RNA and based on the sequence of the nitrogenous bases, the cell translate very specific and demilited lines of RNA into molecule we call proteins. The latter may be useful in different ways depending on the cell needs. So after discovering this, what did genetic engineering do? Basically, they modified sequences of DNA(genes) to make so that different proteins are being assembled in the cell. This way, you basically have a cell that synthetize whatever you want, it's a little "factory". This method which involves creating artificial DNA and the injection of the latter into a cell(which can also be a bacteria) is used as an alternative way to create pharmaceutical drugs, ormones and so on. The cloning-injection process is also the same method used in agriculture to create genetically modified organisms. The injection on food work as immunization, making it so that it develops molecules resistant to the herbicide effect. Now you have an edible organism that resists to herbicide(so you can use it to kill weeds) but it develops unnatural proteins, which we may eat if we buy this type of product. Many biologists claim that this is dangerous for our body, other tolerate it. Personally, I avoid them when possible: I think that if nature made it that way, that's how it's meant to be.
