Get accessDNA stores information to build peptide chains as codons (three nucleotide bases per codon)
Each codon represents a specific amino acid (but each can be encoded by more than one codon)
- There are also stop codons: polypeptide chain terminators
- A gene is part of DNA that directs the sequencing of polypeptide chains
- Comprises
- Exons: coding regions
- Introns: intervening regions of variable length
- Enhancer regions: perform regulatory activity
