Here's how it works:
1. Transcription: DNA's genetic code is copied into a messenger RNA (mRNA) molecule.
2. Translation: The mRNA travels out of the nucleus to ribosomes, where it's read and translated into a chain of amino acids.
3. Protein Synthesis: These amino acid chains fold into specific three-dimensional structures, creating proteins. Proteins are the workhorses of the cell, carrying out a wide range of functions, from building tissues to facilitating chemical reactions.
So, while DNA holds the blueprint, RNA is the messenger that carries the instructions and helps build the proteins that perform the tasks.
