DNA strand

DNA, Genes, and Clones

DNA, or deoxyribonucleic acid (pronounced dee-ox-ee-rye-bo-noo-clay-ic acid), contains instructions for everything our cells do throughout our lives. But what is DNA? It is a long molecule made of two twisting, paired strands. Each strand is made of four chemical units, called nucleotide bases. The four chemical units are strung together in a precise order, just as letters string together to make specific words. Each of your genes contains a segment of DNA that is typically several thousand base pairs long! A genome is all the DNA combined - your complete genetic inheritance.

Scientists are now spending a lot of time studying genes and DNA because that will help us learn more about ourselves and help us stay healthy. The NIH Human Genome Projectlink to a non-NIEHS site, of the National Human Genome Research Institute (NHGRI), National Institutes of Health, has started a worldwide effort to determine how many genes we have, how our cells work, how living things evolve, how single cells can develop into such complex creatures (like you!), and what exactly happens when we become sick. The NHGRI studies should also help us find new ways to prevent and treat diseases.

But our genes are not the only thing that determines whether we will be healthy or sick. Our environment and how it reacts with our genes is also very important. So the National Institute of Environmental Health Sciences has started an Environmental Genome Project to help us understand which genes are more likely to be affected by our environment. And those studies will help us understand why some people get sick from exposures (like cigarette smoke), but others do not.

As for cloning (creating something genetically identical to something else), only animals have been cloned so far. But even if you had a clone, YOU could still be healthier than someone just like you genetically if you provide a better environment for yourself. Here are some ways to do that:Dolly
  • Always wash your hands before eating or preparing food and after using the bathroom -- this is your best protection against food-borne infections.

  • Don't smoke -- and don't allow smoking around you! Second-hand smoke may affect you and unborn babies too. (Learn About the Dangers of Smoking from Mama Didn't Know and Smokefree Kids.)

  • Make sure your home is free of lead and allergens, like dust mites, cat dander, and cockroaches if you are allergic to them.

  • Wash raw fruits and vegetables carefully -- particularly if grown near your frequently sprayed roses

  • Be sure to eat five or more fruits and vegetables a day to reduce your risk of cancer. Popeye says "I yam what I yam!" -- but remember, he still eats his spinach for good health.

Web Weather for Kids Contest Non-NIEHS Site
Middle schoolers from around the USA are being invited to join Boulder,Colo., students in going head to head against a Denver television meteorologist in an on-line weather forecasting contest. The contest is open to anyone born between 1986 and 1991. Mike Nelson, an on-air meteorologist at KUSA-TV in Denver will join middle schoolers in predicting the weather each day between February 8 and 11. Each participant will predict highs and lows and give a thumbs up or down for precipitation the following day at Denver International Airport, using data available on the Web site. Scoring is based on how close each participant comes to forecasting Denver’s high and low temperature each day of the four days, and whether rain or snow does or does not fall.
