The shape of DNA is really interesting and super important for how it works!

1. Structure

• Twisted Ladder: Think of a ladder that is twisted. The sides of the ladder are made of sugar and phosphate, while the steps (or rungs) are made of pairs of nitrogen bases. These pairs are A with T and C with G.

2. Stability

• The twisted shape helps keep DNA stable and safe inside the cell's nucleus, which is like a tiny control center for the cell.

3. Replication

• When a cell divides, the two strands of DNA can easily pull apart. This allows each strand to be used as a guide to make new DNA.

Example: Imagine your favorite recipe. Just like you need to follow the steps to make sure the dish comes out right, the structure of DNA makes sure that genes are copied correctly for the traits you have!
