The shape of DNA, which looks like a twisted ladder or a double helix, is really important for how it works. Here’s why:
Stability: The spiral shape helps protect the DNA from damage. Imagine a ladder that’s twisted; the steps (called base pairs) are held tightly, which keeps them safe.
Replication: Each side of the ladder can be used to make a new side. When a cell splits into two, the double helix opens up to let the DNA copy itself accurately.
Information Storage: The order of the building blocks (A, T, C, G) along the strands carries important genetic information. Because the double helix is compact, it can store a lot of information in a small space inside the nucleus of the cell.
All these features make the double helix super important for life!
