This document discusses protein synthesis through the process of transcription and translation. It explains that genes provide the code for building proteins from amino acids using triplet base nucleotides called codons. Each codon carries a single specific amino acid. The codon sequence in a gene is transcribed into mRNA which is then translated by ribosomes to assemble the amino acids in the specified order to form a protein. An example gene sequence and corresponding codons/amino acids are provided to demonstrate this process.
