Understanding What a Gene Is
A gene is a small section of DNA that carries instructions for how the body grows, develops, and functions. Genes act like tiny blueprints inside every cell.
What Genes Do
Each gene contains information that tells the body how to make specific proteins. These proteins control traits such as eye color, height, and even how your cells work.
Where Genes Are Found
Genes are located on chromosomes inside the cell nucleus. Humans have thousands of genes that together form the complete set of instructions for the body.
Why Genes Matter
Genes influence your physical traits, health, and how your body responds to the environment. Some genetic changes can cause or prevent certain conditions.
Genes and Inheritance
You inherit genes from your parents, which is why family members often share similar features or tendencies. Each parent contributes half of your genetic information.
The Simple Takeaway
A gene is a segment of DNA that contains instructions for building and running the body. It shapes traits and helps guide how life works at the smallest level.
