A gene is a specific sequence of nucleotides within a DNA molecule. These nucleotides provide the genetic information. A polypeptide is a chain of amino acids. A gene codes for a polypeptide. This coding process involves the transcription of the gene's DNA sequence into messenger RNA (mRNA). The mRNA then undergoes translation, where the mRNA sequence is read by ribosomes and the corresponding amino acids are assembled into a polypeptide chain. This process is known as the central dogma of molecular biology: DNA → RNA → Protein. Therefore, the sequence of nucleotides in a gene dictates the sequence of amino acids in the polypeptide.
