Here's how it works:
1. Transcription: DNA contains the genetic code for making proteins. mRNA acts as a messenger, copying this code from the DNA in the nucleus. This process is called transcription.
2. Translation: The mRNA then travels out of the nucleus to the ribosomes in the cytoplasm. Here, the mRNA code is "translated" into a sequence of amino acids, which are the building blocks of proteins.
3. Protein Synthesis: This process, called translation, results in the creation of a protein based on the DNA's original instructions.
So, mRNA is the crucial intermediary that carries the genetic information from DNA in the nucleus to the ribosomes where protein synthesis takes place.
