Gene Expression Analysis and DNA Microarray Assays
If we want to understand a biological organism, we turn to the expression of its genome. Which genes are being expressed, and in which cells, and when? How does this differ between a normal cell and a cancer cell? We have incredibly...

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...

Mitosis: How One Cell Becomes Two
We know that we are made of cells. But we start out as just one tiny little cell in the womb. How does that become enough cells to look like a baby? And how does that baby get enough cells to become an adult? The answer is mitosis! This...

The Cell Cycle and its Regulation
Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad....
