* Transcription is the process of creating mRNA from DNA. DNA contains the genetic code, but it cannot directly participate in protein synthesis. Transcription copies the genetic information from DNA into mRNA, a messenger molecule that can move out of the nucleus and into the cytoplasm.
* Translation is the process of using mRNA to create proteins. The mRNA sequence acts as a blueprint, providing the instructions for the ribosomes to assemble amino acids into a specific protein.
Think of it like this:
1. Transcription: You have a cookbook in the kitchen (DNA). You need a copy of the recipe for the cake (mRNA) to take to your friend's house (cytoplasm).
2. Translation: Your friend uses the recipe (mRNA) to bake the cake (protein) with the ingredients (amino acids).
In summary:
* Transcription creates the mRNA "recipe" that carries the genetic code from DNA.
* Translation uses the mRNA "recipe" to build the protein.
Without transcription, there wouldn't be any mRNA to serve as the blueprint for protein synthesis, and translation couldn't occur.
