you taught me more in this 10 minute video than my teacher did in 2 weeks

@OilersLBA

Again, Bozeman Science saving me in biology.. As a guy studying Pscyhology, and whom has no experience with biology what so ever I simply could not have done without you! And, also, I learn much better watching your videos than listening to lectures. Thank you, Mr. Andersen! 

@NaviTheKitty

You taught me this stuff in 10 minutes and i fully understand when my teacher taught it in a week and i had no clue what was going on thank you savior

@RDRWindwaker

Your high school teaches should be thankful for having you, Paul. I learned more in ten minutes than I did in an entire lecture from my biology professor

@backstreetfan2887

Mr. Anderson refers to an "A protein" however the A, B, and O antigens are definitely carbohydrates, not protein.
Some people in the comments are saying "it is a glycoprotein" however I checked my molecular biology and biochemistry textbooks and they say that the oligosaccharide can be attached to a lipid or a protein.  The gene involved in ABO blood types codes for an enzyme (glycosyltransferase) which can add a monosaccharide to the O antigen.  If you have the A allele you have the transferase that adds N-acetylgalactosamine to the O antigen. If you have a B allele you have a transferase that adds galactose to  the O antigen.  People with AB blood type have both transferases and therefore both A antigen and B antigen.

I love this guy. Mr. Andersen...please be my college professor! Or at least show my current instructors how to teach students better!

@altair2594

i always get here when im lost in medical biology.. thank you so much!!

@brandontran4929

Watched this video in AP Bio, now i'm back to watch it during Pharmacy School

@charlovespink

I couldn't do my assignments without your videos!

@floodbeforethestorm

Thank you for making these videos and being a better teacher than my actual biology teacher. I learn more from your videos than a week of class

@jessyc6779

Thanks! I have a quiz tomorrow. The chapter is literally named after Mendell, but it goes way deeper than that. So this was a great review. :)

@boogieman3498

This was extremely helpful. Im studying for my PBMT (Perioperative blood management technologist) test and this was so confusing for me to understand when I saw it in my book. This video made it very simple. Thank you! Is there any other videos you would recommend that would be helpful to my studies?

@arianarice4911

Thank you!!! That clears the whole antibody vs antigen thing right up!

@nilsdeiters5473

Thanks, what a legend this man just made my day

@schoolwithapril9531

Thank you!  I am doing a blood typing lab today in class and I wanted to explain this better to my kids.

@aversion91

Mr Anderson, You are doing a wonderful work....i am sure it is helping many people like it is helping me........
 

@Starquasia232

You have been so much help this semester, thank you dearly. You make bio fun and especially with the colored images you use

@supergbonin

Better than my teacher could ever teach it. Thank you

@SarcasticSean

Thanks. I have a test tomorrow. Now I am ready for it.

@Bozemanscience1

Check out the AP Biology Lab playlist.  It is near the bottom.  Hope this helps.
