Genetic Science

If you're studying genetics, molecular biology or a related field, odds are good that you will need to learn how to read a codon chart (aka codon table) to better understand the genetic code.

According to the Centers for Disease Control and Prevention, the average height in the United States is 5 feet, 9 inches (1.75 meters) for adult men and 5 feet, 3.5 inches (1.61 meters) for adult women. But some people can reach heights upwards of 7 or 8 feet (2.1 to 2.4 meters)!

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?

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.

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?

What does it take to be considered a genius? Were the Mozarts and Monets of the world born with it? Or did their environment shape who they became?

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.

You yearn to peer out the window of an SUV and watch a Tyrannosaurus rex lumber into a clearing. Your home movie of said event would be a YouTube sensation. Could it ever happen?

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?

Chimps share almost 99 percent of our genetic makeup. What makes up that tiny, 1 percent difference? What are the things that differentiate us from other great apes?

One day you can digest dairy, and the next, milk makes you sick. The culprit behind this crime against milk? Gene regulation. But how do certain traits just switch off?

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?

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?

More than 50 years have passed since Watson and Crick untangled the structure of DNA and five years have elapsed since scientists finished sequencing the entire human genome. What have we figured out about our genetic material?
