From the flu to COVID-19, viruses are a major threat in our everyday lives. In today’s episode of Crash Course Biology, we’ll learn why viruses are like genes in a box, and how they invade and spread between cells. We’ll also discover...

A lot of our videos include the disclaimer "Mice aren't people." But why do we keep saying this, and if rodent studies aren't effective, why do we keep using them?

In this video Paul Andersen explains how the CRISPR/Cas immune system was identified in bacteria and how the CRISPR/Cas9 system was developed to edit genomes.

A lot of our videos include the disclaimer "Mice aren't people." But why do we keep saying this, and if rodent studies aren't effective, why do we keep using them?

The media have been talking about “genetically modified humans” and “designer babies.” But what they’re really talking about is germ-line engineering: a process that could help eliminate heritable diseases. So why do some scientists want...

In part 4 of our special series on human ancestry and evolution, we look into the future. Now that genetic engineering tools like CRISPR allow us to edit our genes, how will that impact human evolution going forward? Are designer babies...

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but...

Explore the science of the groundbreaking technology for editing genes, called CRISPR- Cas9, and how the tool could be used to cure diseases. -- From the smallest single-celled organism to the largest creatures on Earth, every living...

The CRISPR-Cas9 system, adapted from a bacterial defense mechanism, uses Cas9 nuclease and a guide RNA (gRNA) to target and cut specific DNA sequences for genome editing. Cas9, guided by the gRNA, binds to complementary DNA and creates...

Viruses and bacteria have their own set of characteristics that distinguish them. But what are those differences? Well, in this video, we will cover the main differences between those 2 groups of microbes.

We've learned about a few techniques in biotechnology already, but the CRISPR-Cas9 system is one of the most exciting ones. Inspired by bacterial immune response to viruses, this site-specific gene editing technique won the Nobel prize...

In this video, I do a very basic explanation of how the Coronavirus (COVID-19) is tested, according to the CDC's protocol.

Most of us know about viruses, and that they spread disease. But what is a virus exactly? Is it alive? How does it infect a host? There's a lot to discuss here! Take a look.
