DNA, or deoxyribonucleic acid, is made up of four main parts:
Nucleotides: These are the tiny building blocks of DNA. Each nucleotide has three parts: a sugar, a phosphate group, and a nitrogen base.
Nitrogenous Bases: There are four types of these bases: adenine (A), thymine (T), cytosine (C), and guanine (G). A always pairs with T, and C pairs with G. You can think of these pairs as the “rungs” on a ladder.
Double Helix Structure: DNA has a special twisted ladder shape, which helps it stay strong and fit neatly inside our cells.
Antiparallel Strands: The two strands of DNA run in opposite directions. This is important for copying DNA and how it works.
All these parts work together to carry genetic information. This information helps guide how all living things grow and function.
