Have you ever wondered how living things are made? How your hair color is determined or why you have two arms and two legs? The answer lies in something called DNA.
DNA is short for deoxyribonucleic acid. It is a molecule that contains all the instructions to create and maintain living things. DNA is found in every cell of every living organism, from humans to plants to bacteria.
DNA is responsible for many important things. It determines things like our eye color, hair color, and even how tall we will be. It also controls how our bodies work, like how we grow and how our organs function.
DNA is made up of long strands that look like a twisted ladder. This is called the double helix structure. The sides of the ladder are made up of sugar and phosphate molecules, and the rungs of the ladder are made up of pairs of nucleotides. There are four different nucleotides: adenine, thymine, guanine, and cytosine. These nucleotides pair up in a specific way: A always pairs with T and G always pairs with C.
Every person has their own unique DNA, which they inherit from their parents. Half of a person's DNA comes from their mother and half comes from their father. This is why children often look like a combination of their parents.
Scientists study DNA in a variety of ways to learn more about living things. One way they study DNA is by extracting it from a cell and analyzing its sequence. This helps them understand how genes work and how they are related to different traits.
DNA may seem complex, but it's what makes us who we are. It's what gives us our unique traits and it's what makes us different from every other living thing on Earth. By studying DNA, scientists can learn more about the world around us and how living things function.
