Episode notes
Cells Contain Billions Of Proteins
- Human cells contain enormous numbers of protein molecules; rough estimates are about 10 billion per cell.
- Protein counts vary by cell type but are orders of magnitude higher than intuitive guesses.
mRNA Is Often Larger Than Its Protein
- Physically, mRNA molecules are larger and heavier than the proteins they encode.
- Three nucleotides code one amino acid and nucleotides weigh more, so mRNA can be ~10× bigger than the protein.
Tiny Peptides Can Be Functional
- Proteins can be extremely small, with functional peptides like somatostatin at 14 amino acids.
- Microproteins under ~100 residues exist and can still adopt stable, biologically active shapes.
