FAQ about biology olympiads
Hi guys, Most of new students do not know much about how to take place in biology olympiad or what to read or etc. Here I will try to answer as many questions as I can and if you do not find anything, just leave a comment bellow. So let’s get started. What is the IBO? The International Biology Olympiad …
Life cycle patterns
Hi, Let’s review some points about organisms’ life cycles. A life cycle is a series of changes in form that an organism undergoes, returning to the starting state. Transitions of form may involve growth, asexual reproduction, and/or sexual reproduction. More about life cycles can be found HERE. https://www.cabrillo.edu/~ncrane/bio1c/botPDFs/Labs/bacteria,%20cells,%20protists,%20lifecycles/Life%20Cycle%20Patterns.pdf http://waynesword.palomar.edu/lmexer8.htm http://en.wikipedia.org/wiki/Biological_life_cycle
Introduction to mycology
Hi, Only a few of us pay attention to one of the most abundant organisms on the planet – fungi. In national olympiads you quite often can find tasks about fungi, however, in the IBO you may be asked to classify them or choose right answers from multiple choice about they properties as well as reproduction mechanisms and structures. To …
Glycolysis overview
Hello, Let me introduce by far the most important metabolic process of all cells -glycolysis. Glycolysis is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy released in this process is used to form the high-energy compounds ATP and NADH.The glycolysis pathway can be separated into two phases: The Preparatory Phase – in …
SDS PAGE tutorial
Hi there, If SDS PAGE sounds like a ridiculous combination of letters, you urgently need to decipher what these letter mean and understand the mechanism of this technique. Firstly, watch the video. Then flick through the notes. http://web.mnstate.edu/provost/BiochemistryLabI.html http://en.wikipedia.org/wiki/Polyacrylamide_gel_electrophoresis A good tutorial about gel electrophoresis can be found HERE.
Protein Purification Tutorial
Hey, During the IBO practical you may be asked to perform a protein purification and then make some calculations. Thus, let’s introduce yourself to protein purification. Firstly, read the notes. http://web.mnstate.edu/provost/BiochemistryLabI.html Then watch a video to visualize how this process appears in a lab.
Maths in laboratory
Hi, I have already posted some papers describing how to calculate dilution factors, pH and etc. However, this handout is concise but handy for quick revision. Take a look. http://web.mnstate.edu/provost/BiochemistryLabI.html
Pipetting
Probably the first thing you will do when you go to the lab is to take the pipettor and measure the volume of some kind of solution. So let’s review the main steps how to deal with pipettors. http://web.mnstate.edu/provost/BiochemistryLabI.html Then take a look at this video. And this one, too.
Gene transfer in Bacteria: Transformation, Transduction and Conjugation
Hi, Let’s delve into microbiology and learn about gene transfer mechanisms: Transformation, Transduction and Conjugation. http://pathmicro.med.sc.edu/mayer/genetic%20ex.htm Some good information with pictures can be found HERE.
