DNA has a special shape called a double helix. This shape is very important for how traits are passed down from parents to their children. Let’s break it down:
Building Blocks: DNA is made up of tiny parts called nucleotides. Each nucleotide has three parts: a phosphate group, a sugar, and one of four bases (A, T, C, or G).
Base Pairing: The bases connect in pairs. A always pairs with T, and C always pairs with G. This pairing creates the steps of the helix and helps store genetic information.
Copying DNA: When cells divide, the DNA unwinds and makes a copy of itself. This way, each new cell gets an exact copy of the DNA. This process is really important for passing down traits from parents to kids.
This amazing double helix structure helps us understand how traits are passed down through generations!
