What is the genetic code? How was it deciphered?

This video is about the genetic code and how it was discovered. It explains how to use the genetic code table when reading mRNA. It also talks about the experiments of Nirenberg, Khorana, and Leder that led to the genetic code’s discovery.

How do we know DNA is the genetic material?

This video outlines three main experiments that contributed to the knowledge that DNA transfers information from one generation to the next, discovered years before the complete structure of DNA was even known. Learning some key pieces of genetics history is not only helpful for exams but also influences how we think about studying novel findings and appreciating scientific advances we take for granted today.
