This video/slideshow helps you discover exactly how HIV infects a cell and replicates itself using reverse transcriptase and the host's cellular machinery. [4:52]
A brief video explaining the origins of the HIV virus. [1:12]
A brief video explaining mosquito control in Nicaragua. [1:01]
A look inside the birth and life of a tumor. See how the growth begins, and how blood vessels form to support the tumor. [1:12]
This is an interactive video that describes the factors that affect our skin color. There are five points in the video where students can pause the video to learn further information about the concepts discussed. [3:32]
This slideshow helps you discover the beginning of embryonic development and how it is fertilized, how it grows, and how it, in turn, becomes a pregnancy. [2:18]
A close-up look of an Intracytoplasmic Sperm Injection. [1:25]
A quick video clip that shows the lactase enzyme produced in the small intestine of infants. It digests lactose by breaking it into glucose and galactose. [0:53]
Peter Skewes-Cox, and Dr. Graham Ruby, both in the DeRisi lab, explain state-of-the-art DNA sequencing and bioinformatic technologies. [6:36]
In this lifelike narrated animation, watch what happens inside a mosquito when the malaria parasites reproduce and travel to the salivary glands, ready to infect another human host with the next bite. [4:00]
A first-hand look at living with the HIV virus. [4:46]
Follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults, tracing the origin of the trait to less than 10,000 years ago, a time when some human populations started domesticating animals. [14:52]
See how a microarraying robot delivers hundreds of small molecules to a series of slides. [2:00]
A brief video explaining an innovative mosquito control program in Nicaragua. [1:05]
Classroom resources paired with a ten-minute video highlight the groundbreaking research of physical and genetic evolutionary changes in rock pocket mouse populations. [10:31]
The role of penicillin in the body. [0:33]
Students watch a short animation showing how the pocket mouse adapts and evolves in a changing environment. Includes discussion questions. [0:20]
A close-up look at the removal of a polyp. [0:36]
Since RNA is single-stranded, it can fold upon itself and form structures that are protein-like in both appearance and functionality. [0:33]
General transcription factors, activators, and repressors interact to regulate the transcription of eukaryotic DNA into RNA. [2:05]
