A relation R is antisymmetric if, for all x and y, x R y and y R x => x == y.I.e. no two different elements are mutually related.Partial orders and total orders are antisymmetric. If Ris also symmetric, i.e. x R y => y R xthen x R y => x == yI.e. different elements are not related.

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
