Do you know?
DNA is the fundamental molecule that stores and passes on genetic information. It guides how living things grow, function, and inherit traits from their parents.
What DNA Stands For
DNA stands for Deoxyribonucleic Acid, a molecule containing genetic instructions. It helps organisms grow, develop, and reproduce by passing information from parents to offspring.
Structure of DNA
DNA has a double-helix structure with two twisted strands. Each strand is made of nucleotides, which contain genetic information organized by specific base pair sequences.
Function of DNA
DNA stores instructions for making proteins in cells. These proteins help the body perform essential functions like growth, repair, and responding to the environment.
DNA Bases
DNA has four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). Adenine pairs with thymine, and cytosine pairs with guanine.
Location in Cells
DNA is found in the cell nucleus of most living things. In bacteria, DNA is located freely in the cytoplasm instead of a nucleus.
Genes and Traits
Genes are specific sections of DNA that control traits. These traits, like eye color or height, are inherited from parents and passed to children.
