Transcription - How Our Cells Turn DNA into RNA
In every cell of our body, there’s an amazing process happening constantly – a process called transcription . It’s how our cells read the instructions written in our DNA and convert them into useful messages. If we think of DNA as a giant recipe book containing all the instructions to run our body, transcription is like copying a specific recipe we need at the moment. Let's dive into how this fascinating process works, step by step, in simple words. What is Transcription? Imagine our DNA as a library full of all the information needed to keep us alive and healthy. But we don’t use every bit of information all at once. Different cells need different parts of these instructions. For example, a liver cell needs instructions to process toxins, while a muscle cell requires directions on how to contract and relax. Transcription is the way our body "copies" only the specific piece of DNA information that a cell needs at any given time. This copy is made in the form ...
