What Color Eyes Will
Your Children Have?
Great interactive "eye calculator" to predict what color eyes your children will have.
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?!

Cracking the Code of Life
NOVA Online from PBS.
This two-hour program is divided into 16 chapters. Choose any chapter below and select QuickTime or Real Video to begin viewing.
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
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.
Navigate through this timeline of milestones in genetics, with more
than 90 key events and discoveries. Read short, illustrated stories or
find archival images and original scientific publications.

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.

Build a Family Tree
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.
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.|| |
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.
