How do tiny molecules carry the code of life?
Quick fact
DNA stores genetic information using a chemical code made from four different bases.
Why this is interesting
Inside almost every cell is a molecule containing the instructions that helped build your entire body.

Understanding How do tiny molecules carry the code of life?
Cells use DNA instructions to produce proteins that control structure, function, and biological processes.
A deeper explanation
DNA acts as an information storage system for life. Through processes such as replication and gene expression, cells read genetic instructions to create proteins and maintain the complex organisation of living organisms.
