Paragraph on DNA
Students are often asked to write a paragraph on DNA in their schools. And if you’re also looking for the same, we have created 100-word, 200-word, and 250-word paragraphs on the topic.
Let’s take a look…
Paragraph on DNA in 100 Words
DNA is like a recipe book for your body. It tells your body how to grow, develop, and work. Just like how all the letters in a book make different words, DNA uses four different letters: A, T, C, and G. These letters stand for tiny molecules. They pair up to form ‘steps’ that look like a ladder. This ladder then twists to form a spiral, which we call a double helix. So, DNA is a long spiral ladder that holds the instructions for everything in your body. It makes you who you are!
Paragraph on DNA in 200 Words
DNA is like a recipe book that tells our bodies how to grow, develop, and work. It’s a special kind of molecule, or tiny piece, found inside the cells of our bodies. Every living creature, from a tiny ant to a huge elephant, has DNA. People’s DNA is like a blueprint, or detailed plan, that makes each person unique. It decides things like the color of our hair, the shape of our nose, and even if we can curl our tongue or not! DNA is coiled up in a shape that looks like a twisted ladder, we call this a double helix. It’s made up of four different parts, like letters, that pair up to create the steps of the ladder. These pairs are called A-T and C-G. In a human body, there are about 3 billion of these pairs! All these pairs are packed into 23 pairs of chromosomes, which can be imagined as 23 recipe books! So, DNA is super important and helps to make each and every one of us special in our own way.
Paragraph on DNA in 250 Words
DNA, short for deoxyribonucleic acid, is like a blueprint for all living things. Imagine it as a unique recipe that makes you, you. This recipe is written with only four ingredients, called bases, represented by the letters A, T, C, and G. These letters stand for adenine, thymine, cytosine, and guanine. They pair up in a specific way: A with T and C with G, creating a twisted ladder shape, which scientists call a double helix. In humans, DNA is packed into 23 pairs of chromosomes inside each cell’s nucleus. These chromosomes are like chapters of the recipe book, and each one carries different information. When cells divide, the DNA copies itself so each new cell has the same instructions. Sometimes, mistakes or changes, called mutations, can happen in the DNA. These can lead to differences in traits like hair color, height, or even cause diseases. Scientists study DNA to understand how these changes affect our health. They use DNA to solve crimes by comparing DNA found at crime scenes with suspects’ DNA. Also, they can trace our family history because we inherit DNA from our parents. Understanding DNA helps us know more about the life around us, from humans to plants and animals. It’s like a language of life, telling us how living things grow and function.
