DNA
Why do you have your mom's eyes or your dad's hair color? The answer is in your DNA.
Deoxyribonucleic acid, in short, DNA, is the blueprint for your body. It carries instructions that tell your cells how to grow, repair, and function.
DNA is located in the nucleus, a central compartment that acts like the cell's control center. In some organisms, like bacteria, DNA floats freely in the cytoplasm because they lack a nucleus.
DNA is made of small subunits called nucleotides. Each nucleotide has three parts: a sugar, a phosphate group, and a nitrogenous base.
There are four types of nitrogenous bases: Adenine, Thymine, Cytosine, and Guanine, which pair up in a specific way: Adenine pairs with Thymine, and Cytosine pairs with Guanine.
DNA is arranged in a long, coiled structure called a double helix, which is a popular image you might have seen already.
The sequence of the nitrogenous bases in DNA has the instructions for building and maintaining an organism. These instructions are like a code that determines our physical appearance. We call these codes genes.
