Your DNA contains all the instructions your body needs to function. In this episode of Crash Course Biology, we’ll figure out what this giant instruction manual looks like and how this three-billion-letter code gets copied into your...

One of the most bizarre proposals for life not as we know it doesn’t even use atoms. It proposes that fundamental kinks and defects in the fabric of the universe - cosmic strings beaded with magnetic monopoles - may evolve into complex...

3 billion base pairs is a pretty typical genome size for organisms like us, but there are a few plants and animals with genomes so huge they completely blow this number out of the water. Hosted by: Olivia Gordon

We've made some great strides in understanding the human genome, but before we can tackle genetic engineering, we have some "chicken and egg" problems to figure out. Hosted by: Hank Green

In 1993, scientists cracked open a piece of amber, took out the body of an ancient weevil, and sampled its DNA. Or, at least, so we thought. It took another few decades of research, and a lot of take-backs, before scientists could figure...

Explore the steps of transcription and translation in protein synthesis! This video explains several reasons why proteins are so important before explaining the roles of mRNA, rRNA, and tRNA in the steps of protein synthesis! Expand...

Explore electrophoresis with The Amoeba Sisters! This biotechnology video introduces gel electrophoresis and how it functions to separate molecules by size. Expand video details for table of contents. Major Points in Video: Intro 00:00...

Hank tells us three surprises about human DNA which we learned because of the Human Genome Project.

There’s more to DNA than just the double helix we know and love: under some conditions this familiar molecule can take on unfamiliar forms, each of which can have a different impact on our health.

We've made some great strides in understanding the human genome, but before we can tackle genetic engineering, we have some "chicken and egg" problems to figure out.

What is genomics? How will it affect our lives? In this intriguing primer on the genomics revolution, entrepreneur Barry Schuler says we can at least expect healthier, tastier food. He suggests we start with the pinot noir grape, to...

Curious about genetics? Dig in a little deeper with this special SciShow Talk Show featuring science writer and 2016 Stephen Jay Gould prize winner Carl Zimmer talking about what he did after receiving himself on a hard drive.

In this video Paul Andersen answers this question about chromosomes. He explains how the base pairs of DNA form genes which are organized into the chromosomes of the overall genome.

In this episode of SciShow, we're going to investigate a murder. But first, we're going to have to learn all about forensics, the use of science in criminal law -- and the real-life version is a little different from what you might see...

Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

Deoxyribonucleic Acid, the molecule that stores and passes on genetic information that determines how an organism develops and functions.

How does our DNA make us unique, and how is this unique genetic information passed on when cells divide? Biology - Cells And DNA - Learning Points. Deoxyribonucleic Acid (DNA) molecules are found in chromosomes within all our cells. DNA...

The Joint Genome Institute is part of the largest biomedical project ever undertaken, the Human Genome Project. This project aims to map and identify the 30,000 genes that make up the human blueprint. By determining the sequences of the...

DNA holds enough information to make a person, but can we use it to store large amounts of our data?

Transcription (Partial; no markings; as done in lab)

It introduces the goals and methodologies of the human genome project and lists the salient features of the human genome.
