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...

The DNA Damage Response | Repair the DNA or Commit Apoptosis?
DNA damage is inevitable. But what happens inside the nucleus when the DNA becomes damaged? Here we discuss the biochemical processes that occur and how the cell decides whether to attempt DNA repair or undergo apoptosis.

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 -...
