Central dogma: DNA → (transcription) → mRNA → (translation) → Protein.
Transcription
- RNA polymerase binds promoter
- One strand (template) used
- Uracil replaces thymine in mRNA
Translation
- Start codon: AUG (methionine)
- Stop codons: UAA, UAG, UGA
- tRNA brings amino acids; ribosome catalyses peptide bonds
- Genetic code is degenerate (multiple codons per amino acid)
