21. Knowledge & Advancements In DNA
- Includes: Discovery Of Double-Helix, DNA Profiling/Forensics
One of the most important things that have come to pass in the world of DNA is our scientific breakthroughs in Forensics. Helped by DNA, we’re able to accurately use even the smallest traces of DNA to find out who might have committed a crime. While this can be done with blood, it can also be done with spit, hair, fingerprints, and much more.

However, we also have used DNA outside of criminal justice to find out our ancestries too. Before all of this really began, we make a huge breakthrough in molecules. This is where we are able to look at the double-helix DNA model. We even know of three forms of DNA, the A-form, B-form, & Z-form. All of this has helped us advance science in massive ways, one of which we’ll address later in this article.
