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...

How Can Smoking Cause Lung Cancer
Here, I present one of the most important mechanisms for the carcinogenic properties of cigarette smoking. P450-oxidized metabolites of benzo[a]pyrene damage DNA and can induce mutations leading to the uncontrolled cell growth associated...

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...

What are Mutations and what are the different types of Mutations?
A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...
