central dogma

Central dogma is a way of understanding how information moves around in cells. It explains how genetic information gets used to make proteins. Proteins are special molecules in cells that carry out important jobs.

First, the information stored in DNA (the genetic code) is copied. This copy is called messenger RNA, or mRNA. The mRNA is like a package that brings the genetic code from the DNA to a cell's factory, called the ribosome.

At the ribosome, the mRNA unloads the genetic code in the form of a recipe. The ribosome reads the recipe and uses it to make a protein. The protein is like a special equipment that does different jobs in the cell.

This process of getting information from DNA to proteins is called the central dogma.
