Genetic Science

Genetics is the study of cellular science. It furthers our understanding of how DNA and the genetic make-up of species and can lead to cures for diseases and shape our future.

Before the widespread use of DNA, establishing the paternity of a child was a tricky business. Ever heard of the oscillophore?

After scientists announced the first draft of the human genome, people began to wonder how our new understanding of DNA would change life. Several research institutes stated the accomplishment would revolutionize science and modern medicine -- but how, exactly?

What's more fun than looking at pictures of DNA and celebrities? Check out Dolly, dimples and dominant and recessive traits in this fun gallery charting how genetics play out in humans (and a few animals).


How can children from the same parents look so different? I mean, why don't all kids from the same parents look exactly alike, since the parents just have one set of chromosomes each and they don't change?

A Punnett square helps predict the possible ways an organism will express certain genetic traits, such as purple flowers or blue eyes.

CRISPR is the genius behind innovations that seemed impossible a decade ago. Could you grow tomatoes with the kick of hot sauce or ferment wine that doesn't cause a hangover? That's just two of the things scientists are looking into.

When the traffic lights are functioning, drivers (usually) behave. Break a light, and everything comes to a standstill. Within our bodies, we could liken that broken traffic light to a DNA mutation — one that has the potential to mess up our body's everyday operations.

We've been raised with the belief that death is inevitable, so we must consider the legacy of what we'll leave behind. But what if you had unlimited time to pursue your life's work? What if you didn't have to die?

Ever since I took biology in high school I have wondered -- why do humans (and plants and animals) have two of every gene, and why is one "dominant" and the other "recessive"? How does my body know which one is dominant? How does it pick between the

The physical you is a result of your DNA, and your DNA is part of the human gene pool. Find out what the "gene pool" really is and what happens when it shrinks.

This week, a group of London-based scientists requested official permission to begin a three-year study involving stem cells derived from human-cow hybrids.

Hereditary illnesses are passed down from parents to their children like gene traits, and children might inherit a disease even though their parents never suffered from its symptoms. Learn about hereditary illnesses.

It sounds kind of great, right? Imagine everything you and yourself could get done. You'd be masters of the world -- wouldn't you?

Much like Noah, researchers are stockpiling the genes of Earth's living creatures, loading them into state-of-the art facilities and freezing them. Are scientists saving them for a rainy day?

Can humans live forever? No, but thanks to the discovery of the Hayflick limit, we know that cells can conceivably divide forever without dying.

Given the choice, would you rather have been born with a different eye color, hair color or skin tone? Of course, you didn't have these options, but could you have them for your own children?

The CBS drama "CSI: Crime Scene Investigation" routinely uses cutting-edge technology to solve crimes, including collecting and analyzing DNA evidence. But catching a criminal using DNA evidence is not quite as easy as "CSI" makes it seem.

Cloning is the process of making a genetically identical organism through nonsexual means. In this article, we will examine how cloning works and look at possible uses of this technology.

What is the difference between a hardwood and a softwood? How hard does a tree have to be to be considered hardwood?

With movie titles like "Attack of the Clones" and "The Clone Wars," it's no wonder human cloning makes us anxious. As scientists make startling discoveries cloning animals, are humans next?

Who hasn't fantasized about bigger biceps? Killer abs? A rear end you could bounce a quarter off? But would you tamper with your genes to achieve that buff body?

How would you like to be the person responsible for changing science and Western civilization? With the "Origin of Species," Charles Darwin did. How did this English gent become the reluctant ambassador of evolution?
