DNA Replication

Paul Andersen explains how DNA replication ensures that each cell formed during the cell cycle has an exact copy of the DNA. He describes the Meselson-Stahl experiment and how it showed that DNA copies itself through a semi-conservative process. He then explains how multiple enzymes, like DNA polymerase, helicase, primase, ligase, and single strand binding proteins copy DNA. He also differentiates between the leading and the lagging strand. He explains how DNA is anti-parallel in nature and how eukaryotic cells have multiple origins of replication.

Not everyone is as clever as you are, some may need to put in extra hours or gain different perspectives on how things work and bozeman science does put things in a clearer perspective. If you are so clever and only need the classes, why are you here anyway?

I got more from this than the 2 periods of class I got. (My teacher is good, it's just I get bored once the teacher starts to talk about something else or make their analogy too long and then i just stop listening altogether)

All your videos are great to learn in an easy and simple approach.A little correction for the picture at 4:59: In eukaryotic DNA polymerase, Pol ε (epsilon) is to extend the leading strand during replication, therefore Pol δ (delta) in the picture should be Pol ε (epsilon). Pol α (alpha) in the picture could be right polymerase on the lagging strand as Pol α starts replication elongating the primer with ~20 nucleotides. But, if it is more than 20 nucleotides, Pol δ (delta) primarily replicates the lagging strand, therefore Pol α (alpha) in the picture might be replaced by Pol δ (delta) as well
