Secrets: Difference between revisions

*If you don't know the answer directly, try to put yourself in the '''mind of the creator''' of the question, who often wants to prove a certain point, often something unexpected, and favor answers that conform to such an intention.

*If something is '''hard''' to memorize, and it is not memorization-worthy besides for exams, skip it, and aim for passing the exam based on things that are easier to remember, such as questions that you can use reasoning to answer correctly. On the other hand, if something is hard to memorize, it will likely be forgotten relatively fast as well.

File:Autosomal recessive inheritance.png|An example of where reasoning can be used to memorize a topic is that hereditary defects in enzymes are generally inherited in an autosomal fashion because there are more non-X chromosomes than X-chromosomes, and a recessive fashion because the enzymes from the functional genes generally work well enough to prevent symptoms.  

File:Autosomal dominant inheritance.png|On the other hand, hereditary defects in structural proteins (such as osteogenesis imperfecta, Marfan's syndrome and Ehlers–Danlos syndromes) are generally autosomal dominant, because they functionally work as beams and chains, so it is enough that some components are defective to make the whole structure dysfunctional.
