What is (and isn't) a GMO?
Many nations ban them, most people have eaten them, and some actively protest in opposition to their existence, but what exactly is a genetically modified organism, and what are some things that aren't a GMO but are nonetheless often...

How humans made corn.
Corn or Maize is a staple food in many parts of the world, with total production surpassing that of wheat or rice. But it wasnât always the high yield crop it is today. Ten thousand years ago a grass called Teosinte was domesticated...

Developing Hardier, Weather-Resistant Crops
At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera...

Genetics in Action: Law of Segregation
This video builds on the genetic work of Mendel and takes the student through additional genetic discoveries made in the twentieth century. The Law of Segregation and the Law of Independent Assortment are plainly illustrated. The notions...

Selective Breeding
Selective breeding is also known as artificial selection. It is the process by which humans breed plants and animals for particular genetic characteristics. We have been doing this for thousands of years - ever since we first bred food...

Chromosome Structure and Organization
We've all seen pictures of chromosomes, and we know that they contain DNA. But how do we get from the double helix of DNA to the X-looking shape of a chromosome? Is it just DNA, or are there other things in there? How much DNA is in each...

Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors
We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to...
