Episode notes
Life's Handedness
- All DNA in earthly living things twists to the right, favoring "left-handed" chemistry.
- This "handedness" is called chirality, a mirror-image concept like your face in a mirror.
Mirror Molecules and Cells
- Mirror molecules, unlike their usual counterparts, aren't recognized by body enzymes, potentially lasting longer as drugs.
- Manufacturing these molecules is complex, necessitating a "mirror cell" factory.
Mirror Cell Feasibility
- A mirror cell, though theoretically possible, has never been observed.
- Scientists believe mirror cell chemistry should function but lack definitive proof.
