Hi, In this tutorial you will learn about various methods used in gene transfer in plant cells. http://web.mnstate.edu/provost/
Cell Counting
Hello, In this lesson you will learn how to use a hemocytometer and how to count cells in your culture. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm. Firstly, take a look at a video so that you understand what it is all about. To end with, another good video.
Plant cell cultures
Hi, In the previous post we discussed animal cell cultures and we now proceed to plant cell cultures which have some specific attributes to remember. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm Take a look at the video about aseptic technique while working with plant tissues.
Animal cell cultures
Hello, After some break, we will continue delving into biology. In this lesson you will find out about animal cell cultures. http://web.mnstate.edu/provost/PlantandMamalianTissueCulture.htm. Before we begin, take a look at this video which presents how everything looks in laboratory. To end with, one more video: Human cell vector created by brgfx – www.freepik.com

Population genetics III
Population Genetics is the study of genetic events at the level of the population. Below is a handout which will help you understand population genetics better. http://www.bio.miami.edu/dana/250/25009_16print.html.
Electron transport system
Embedded in the inner membrane of the mitochondrion are a bunch of protein complexes that are involved in electron transport. They make up the electron transport chain (ETC). HERE you will find an amazing website VIRTUAL CELL ANIMATION COLLECTION. Take a look at an electron transport chain (ETC). HERE there is another good video about ETC in mitochondria. Useful animations …
Amino Acids & Proteins
For the hardest part in biology olympiads has always been biochemistry. Thus, I would like you to be the best in this field, so here you will find some good notes of amino acids and proteins from the biochemical point of view.Especially pay your attention to isoelectric point and pK calculations. The isoelectric point, sometimes abbreviated to IEP, is the …
Enzymes
Review a concise and fun slideshow about enzymes before olympiad below. http://rvrhs.enschool.org/ourpages/auto/2013/10/8/45710277/Enzyme%20Notes%201-22.pdf
Behavioral ecology
This lesson is about behavioral ecology. Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures. Most probably during olympiad you will get a situation and you will have to determine what kind of behavior is in the problem. For example, The answer is B …
Biostatistics Part 2
To continue our topic on biostatistics, here I will post some good stuff to learn. Firstly, HERE you will find amazing tutorial. Take a look. Below you will find a simple introduction to chi-square. http://www.dpisd.org/cms/lib4/TX01001079/Centricity/Domain/1059/ChiSquarePractice.pdf http://staff.orecity.k12.or.us/kate.fisher/Ms._Fishers_Website/AP_Biology_files/X2%20Practice%20Problems%20Key.pdf https://sharepoint.ocsarts.net/student/academic/rima_semaan/honors_biology/Lists/Announcements/Attachments/422/Ch%2011%20Genetics%20and%20Statistics%20(Chi%20Square).pdf http://www.colby.edu/biology/bi164/Lab/Lab%204Genetics&ChisquareANSWERKEY.pdf
Biostatistics Part 1
After some break, I came back and would like to suggest you reading about biostatistics. Even though in biology olympiads this comprises only a small part of testing, however, you should know t-test and Chi-square very very well. To begin with, bellow you will find a comprehensive textbook of biological statistics. http://udel.edu/~mcdonald/HandbookBioStat.pdf, A good summarize on P-VALUES AND HYPOTHESIS TESTING. …
Enzyme kinetics
Here you will find some stuff about enzyme kinetics. The study of the rate at which an enzyme works is called enzyme kinetics. http://web.campbell.edu/faculty/chazotte/ http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/EnzymeKinetics.html http://www.columbia.edu/itc/chemistry/chem-c2407/hw/ENZYME_KINETICS.pdf www.glutxi.umassmed.edu/grad/GradKinetics.pdf
