National DNA Day is a unique day when students, teachers and the public can learn more about genetics and genomics! The day commemorates the completion of the Human Genome Project in April 2003, and the discovery of DNA's double helix. Next year, NHGRI will celebrate National DNA Day on April 15.

What Color Eyes Will
Your Children Have?

Great interactive "eye calculator" to predict what color eyes your children will have.

Gene Game

Genes affect how you look, act, and can even affect your health. So, some of the stuff you really like about yourself (and, some of the stuff you don’t) just might be in your genes. Wanna know more?! Play the Game!

Awesome Resource!

 Journey into DNA

This exploration allows you to travel to the tiny world of DNA. Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell.

 Explore a Stretch of Code
The human genome is no more than a string of four letters -- A, T, C, and G -- repeated over and over, more than three billion times. To the untrained eye, these letters, also known as nucleotides or bases, appear meaningless. But when scientists look at our genetic code, they can see an amazing story of human history and our connectedness to other creatures on this planet.  Here, explore an actual stretch of human DNA and see what the experts see.

Sequence for Yourself

Sequencing the human genome is not as easy as A-G-C. The concepts involved, however, are easy to grasp. "Sequence for Yourself" should give you a good idea of the general process.

Fact Sheets

About Science, Ethics, Research Technique and the Institute

The National Human Genome Research Institute (NHGRI) has produced a series of fact sheets to provide an overview of the institute, explore the social implications of genetic research, and explain complex genetic concepts and research techniques to a non-scientific audience. Teachers, students and the general public alike will find the materials clearly written and easy to understand.

DNA Workshop
You Try It!

Build a Family Tree
Men Only

To figure out relatedness, you'll need to compare the order of letters between the DNA sequences to find the differences, then use your powers of deduction to figure out which individuals are most alike.

Create a DNA Fingerprint

 But what exactly is a DNA fingerprint? Well, it certainly isn't an inky impression of a DNA strand. Compared to unimaginably small DNA, a fingerprint is HUGE. So what is it that we're looking at, and how is one of these fingerprints made?

Here's your chance to find out. You'll find out by solving a mystery—a crime of sorts. Solving the mystery involves creating a DNA fingerprint (we'll supply the lab and all necessary materials) and comparing this fingerprint to those of the suspects.

Transgenic Fly Lab

 The lab will familiarize you with the science and techniques used to make transgenic flies. Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms. (Click here for more on experimental design.) The fly glows only when a certain gene involved in circadian rhythms is activated. After making the glowing fly, you will use it to explore basic principles of circadian biology and genetics.


Evolution of the Y Chromosome

How did the human Y chromosome become so small relative to its X counterpart? This animation depicts the 300-million-year odyssey of the sex chromosomes that began when the proto X and Y were an identical pair.

Mendal's Peas

We suggest you start at the beginning to brush up on the basics. But if you just can't wait to play the game, skip ahead to Part 3, The Princess and the Wrinkled Peas.
