Charles Darwin's Idea: Descent With Modification
Now that we've learned about molecules and cells and the simplest forms of life, we are ready to understand how all of life on earth evolved from a single common ancestor. Given our newfound knowledge about the chromosomal theory of...

How Genes are Expressed
Genetic Expression Set: 1. This clip introduces the process of gene expression, whereby information stored in the DNA of a gene is transcribed into messenger RNA and translated into a protein gene product.

MECP2
How do cells control which genes they express? The animation describes a specific example of how, after interaction with proteins, gene expression turns off. Scholars learn about the role of histone proteins and chromatin in the process...

Mit: Blossoms: Tissue Specific Gene Expression
How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or...

Science Friday: What Your Genes Can Tell You About Your Memory
Scientists have identified molecules that assist the formation of long-term memories. Epigenetic markers respond to stimuli and change gene expression, so the memories can be reactivated at a later time. Aired Oct. 5, 2012 [21:33 min]

Bozeman Science: Signal Transmission and Gene Expression
Paul Andersen explains how signal transmission is used to alter both cellular function and gene expression. He uses the example of epinephrine release in humans and how it is used in the fight or flight response.
