Here's how it works:

1. DNA to mRNA: The DNA sequence is transcribed into a messenger RNA (mRNA) molecule.

2. mRNA to Protein: The mRNA molecule travels to a ribosome, where it is translated into a protein. The ribosome reads the mRNA sequence in codons (groups of three nucleotides), and each codon corresponds to a specific amino acid.

3. Amino Acid Chain: As the ribosome moves along the mRNA, it links the amino acids together in a chain, forming a protein.

So, while DNA is the blueprint for life, it's the proteins that actually carry out the functions of the cell and the body.
