Helen O'Neill: The CRISPR genome editing revolution

TL;DR

The journey from bacteria to modern genetic modification technology using CRISPR, with implications for human disease treatments and ethical considerations.

Transcript

so I want to take you on a little bit of a journey back before we had Homo sapiens to homo habilis one of the first men to work a walk on the planet not the best-looking of guys but then he probably was the only one that was on the planet or very few thereof and we want to look at how different our genetic makeup is to theirs and maybe importantly ...
