Have you ever wondered what makes you unique? Why do you have your eye color, or why can you roll your tongue? These special features, called traits, come from your family, like your parents and grandparents. They are written in a special code found in your DNA.
DNA stands for deoxyribonucleic acid. It’s a long, twisty molecule that looks like a spiral staircase, called a double helix. DNA is found in the nucleus of the trillions of cells that make up your body. If you could stretch out all the DNA in your body, it would reach from the Earth to the Sun a hundred times!
DNA is packed tightly into structures called chromosomes. You have 23 pairs of chromosomes in each cell, which carry the instructions for your traits. These instructions come from both your mom and dad, making you one of a kind!
DNA isn’t just in humans; it’s in all living things, like plants and animals. It’s what makes a cat a cat or a dinosaur a dinosaur. DNA is the reason you have blue, brown, or green eyes.
Scientists study DNA to help in many ways. For example, they can look at DNA from a blood sample to find out if someone might get certain illnesses, like cancer. This research can help doctors prevent diseases before they start.
DNA testing is also popular for learning about family history. By looking at your DNA, you can discover where your ancestors came from and how your family has traveled around the world over time.
DNA is important in solving crimes, too. Even if someone tries to hide, they leave behind tiny bits of DNA, like skin or hair, which can help police find them.
Remember the movie Jurassic Park? Scientists used dinosaur DNA from a mosquito in amber to bring dinosaurs back to life. While that’s just a movie, it’s fun to imagine!
DNA helps scientists learn about ancient people and animals. It can tell us what an ancient mummy might have eaten or how a long-necked giraffe got its spots. Farmers use DNA to grow better crops and healthier animals, like cows that give more milk.
DNA is what gives flowers their beautiful colors and roses their thorns. It’s the secret code that makes every living thing special, including you!
We hope you enjoyed learning about DNA. Remember, you are unique and special just the way you are!
DNA Detective: Become a DNA detective by observing traits in your family. Make a list of traits such as eye color, hair color, or the ability to roll your tongue. Ask your family members about their traits and see if you can find any patterns. Do you share any traits with your parents or grandparents? Discuss with your family why you think these traits are similar or different.
Build a DNA Model: Use colorful beads or building blocks to create a simple model of a DNA double helix. Assign each color to represent a different part of the DNA structure, like the sugar, phosphate, and the four bases (A, T, C, G). Twist your model to see how DNA looks like a spiral staircase. Display your model and explain to someone how DNA carries the instructions for traits.
Nature’s DNA Hunt: Go on a nature walk and observe different plants and animals. Choose one plant or animal and think about what traits make it unique. For example, look at the colors of a flower or the patterns on a butterfly’s wings. Draw or take a picture of your chosen subject and write a short story about how its DNA might have helped it develop those traits.
Sure! Here’s a sanitized version of the transcript:

What is DNA for kids, you ask? Well, let me ask you: Who are you? What color are your eyes? Do you have earlobes? Are you tall or not? Can you curl your tongue? Many of your personal traits are inherited, meaning they come from your ancestors like your parents and grandparents. These traits are written in code located deep in your DNA.
In this video, Clarendon Learning explores DNA for kids, where we will discuss what DNA is and where it is found. If you had an electron microscope, you could find DNA deep in the nucleus of the trillions of cells that make up your skin and organ tissues. Your special DNA codes make you one of a kind—unless you’re an identical twin, then of course you’re twice as special!
DNA is short for deoxyribonucleic acid. This is what the DNA molecule looks like: long strands connected by genetic material to form a double helix, which resembles a spiral staircase. You have approximately 10 trillion cells in your body, and if you were to stretch out all your DNA from every cell, it would reach from the Earth to the Sun a hundred times. That is a lot of DNA!
DNA strands are so long that they must be packaged specially to fit into the nucleus of every cell. They are wound up tightly and form structures called chromosomes. A complete set of 23 pairs of chromosomes fits nicely into every cell, and this is what identifies your physical traits—traits from your mother and traits from your father, which make you unique.
DNA is found in all living organisms, both on land and in the sea. It’s what makes a T-Rex a T-Rex or a cat a cat. DNA identifies a bug, a leaf, or a person, and it is what makes you, you. It’s what gives you blue, brown, or green eyes.
DNA research can be valuable in the healthcare industry. DNA material obtained from a blood sample or a swab of saliva from inside your cheek may show a link to certain kinds of cancers. Wouldn’t it be great if genetic research could help prevent cancer before it develops? DNA testing has also become very popular in family history research. Would you like to know what countries your ancestors came from? This kind of work is called genealogy. From a simple drop of saliva, your DNA can show the migration patterns of many generations of family members.
Many people are fascinated to learn the origins of their family tree and where they came from. Every family story is important, and we can also learn how we are all connected. Using DNA material to find criminals has become very important. Even if evildoers try to hide, they always leave traces behind, like blood or skin, and law enforcement can use that to find them.
You might remember in the movie Jurassic Park how dinosaur DNA was extracted from an ancient mosquito trapped in amber. While that may not be realistic, it’s fun to think about. Should we grow dinosaurs today? It’s an interesting thought, but perhaps a bit scary!
DNA technology is also used in archaeology to identify what an ancient mummy may have died from. Consider using DNA and genetic science in breeding animals—cows bred to produce more milk, healthier meat, and crops that yield more fruit and vegetables. DNA is what gives a tulip its blooms and thousands of colors, and it gives a rose its thorns.
DNA is present in a long-necked giraffe and a zebra with stripes. The secret code is all in their DNA. DNA gives you the dimple in your chin and the freckles on your nose, and we like you just the way you are!
