Definition of gene

What is a Gene?

A gene is a tiny piece of information found in our bodies that determines many of our features or traits. It is like a set of instructions that tells our bodies how to grow, how we look, and how we function.

Where do Genes Come From?

Genes are passed down from our parents to us. They are inherited, just like how we inherit certain traits, like the color of our hair, our eye shape, or our height. Each person has a unique set of genes that makes them special and different from others.

Where are Genes Found?

Genes are found in every cell of our body. Inside each cell, there is a tiny structure called the nucleus, which is like the control center. Genes are like the boss of the control center, giving instructions to make proteins, which are important for our body to work properly.

Synonyms for Genes

Genes are sometimes called “genetic information” or “DNA.” DNA, or deoxyribonucleic acid, is the material that makes up our genes. It is like a long ladder with many steps, and each step is made up of different chemicals.

Comparing Genes to Recipes

We can think of genes like recipes in a cookbook. Just as a recipe tells us how to make a delicious dish, genes tell our body how to make every part of us. Each gene is like a different recipe, but instead of making food, it makes us who we are. Just like how a cake recipe tells us how to make a cake and not a pizza, different genes give different instructions to make different parts of our body.


In simple words, genes are the special instructions that make us unique. They determine our hair color, eye color, height, and many other things about us. Think of genes like a guidebook that tells our body how to grow and function. Without genes, we wouldn’t be who we are!
