Molecular Biology

Paul Andersen explains the major procedures in molecular biology. He starts with a brief description of Taq polymerase extracted from the hot pools of Yellowstone Park. He then uses the analogy of the ransom note to explain each of the processes that are required in genetic engineering. He explains how DNA is cut using restriction enzymes and glued using hydrogen bonds. He explains how gel electrophoresis can be used to sort DNA according to length and how the Polymerase Chain Reaction can be used to copy DNA. He finishes with a brief description of DNA sequencing.

Your "real" students are literally the luckiest kids ever. Thank you!!!

[bellawills]

This channel is where I go to before a test

[sarahaghani]

Mr. Anderson, I'm really jealous of your biology students for having a great teacher like you. Thank you so much sir!

[yehyaaljerjawi]

Our teacher doesn't teach he just shows us these videos

[moneyluser]

Finally a briskly paced video without 30min of useless introduction. Thank you!

[peepalfarm]

I wish I had teachers like you for all subjects!

[WithASideOfFries]

Dude. I have a test in an hour and I haven't studied so I'm binge watching your videos and you. Are. A. Godsend!!!

[elyseong]

If it wasnt for your videos, I would have been screwed in my AP Bio class.
I wish you were my real teacher...

[galaandding]

When someone can explain genetics in this simple manner, Someone REALLY understands genetics! Thank you, professor!

[jordyntully]

this video taught me more in 15 mins than I've learned in a month from lectures. thank you so much! the way you speak and explain things is perfect.

[matildaramos]

Got to admire the sheer effort he puts into his videos

[DanielMaly]

I have not seen a better explanation especially for the DNA sequencing. In other videos on youtube they dont explain much perfectly the fact, how dideoxynucleotides help show the letters when running trough gel. Thanks to your emphasis on the importance of lenght and so many varieties of where dideoxynucleotides can bind when the amount of DNA is huge, it helps to imagine how the nucleotides are gonna run trough the gel one by one until the whole order is read. Really good job!

[DorPeer]

One of the most comprehensible biological videos I have ever seen! Terrific.

[hanahleiabach]

Using this to help review before a high bio test and this is a LIFE SAVER

[oliviagrigaux]

Only reason I'm getting an A in my AP Bio class are your videos.Thank you so much!

[parthobiswas]

Moleculer biology was never been so easy. Thanks to you.

[HaryanaEducation]

the way u make the things clear and more easy is just amazing

[mass_oak]

i'm just watching it, couse i have missed this guys. i used watch his video every day when i was in college. definitely brings memories. he is very good explainer.

[kristinmoore]

I think you just saved my microbiology lab grade!

[shaneberrett]

No joke, about an hour or two of lecture in my class left me confused and then 15 minutes of this video made perfect sense
