Here's a breakdown:
* DNA: The blueprint of life, containing the instructions for building and maintaining an organism.
* Gene: A specific segment of DNA that carries the code for a particular protein.
* Protein: A complex molecule made up of amino acids, which perform a wide range of functions in the body, such as building and repairing tissues, transporting substances, and regulating chemical reactions.
How it works:
1. Transcription: The gene's DNA sequence is copied into a messenger RNA (mRNA) molecule.
2. Translation: The mRNA travels to the ribosomes, where it's used as a template to assemble amino acids into a specific protein.
Think of it like this:
* DNA is like a recipe book: containing all the recipes for making different proteins.
* A gene is like one specific recipe: providing instructions for making a particular protein.
* Proteins are like the dishes made from the recipes: performing specific tasks in the body.
