Why are We So Much Chubbier than Other Apes?
Chimpanzees and bonobos may be very close to us humans on the tree of life, but one of our differences is the way we store fat. That difference comes down to types of fat cells and our DNA. Hosted by: Hank Green

What the World’s Smallest Tweezers Tell Us About DNA
DNA isn’t the simple, loose double-helix you might see in a biology textbook, so isolating single strands of it can be next to impossible. But with some simple tricks of physics, scientists came up with a special type of tweezers that...

Mitosis
Paul Andersen describes the process of mitosis. He begins by discussing the importance of the cell cycle in development, regeneration, asexual reproduction and wound healing. He differentiates between haploid and diploid cells and...

HST-AP - Mitosis/Cell Division
Mitosis is an asexual reproduction where a single cell divides into 2 identical cells (if mutation has not occurred) This video covers the process of cell division and all the key players including the nucleus, Chromatin, Chromosomes,...

Visualizing a Nucleosome in Virtual Reality
We've talked a lot about DNA in this series. Building off of our understanding of nucleic acids in biochemistry, we now know that DNA wraps around histones to form nucleosomes, which then supercoil to form chromatin. But what does a...

Chromosome Structure and Organization
We've all seen pictures of chromosomes, and we know that they contain DNA. But how do we get from the double helix of DNA to the X-looking shape of a chromosome? Is it just DNA, or are there other things in there? How much DNA is in each...
