We have come a long way from George Beadle’s “one gene, one enzyme” hypothesis. This video explains how a surprisingly low number of protein-coding genes into a surprisingly large number of protein variations.

Understandably, there has recently been an increased interest in viruses. Here, we will tie our discussion of the Central Dogma of Biology to viruses. The typical flow of genetic information from DNA to RNA to protein is often modified by viruses, which have a variety of genome types.

Building off of the Central Dogma of Molecular Biology episode, we take a close look at RNA and the many functions of these molecules in a cell.

The Central Dogma of Biology provides a foundation for molecular biology. This video goes over the general flow of genetic information, enzymes involved in the process, and an intro to thinking about controlling the rate of each stage.
