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...

Epigenetics
Paul Andersen explains the concepts of genetics. He starts with a brief discussion of the nature vs. nurture debate and shows how epigenetics blurs this distinction. He explains how differentiation of cell types results from the...

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...

DNA Replication: Copying the Molecule of Life
Your DNA needs to be in every cell in your body, so what happens when cells divide? How does each new cell retain all of the genetic information? The DNA is able to copy itself through a process called replication. Let's go through the...
