Size and foreignness are not, by themselves, sufficient to make a molecule immunogenic; other properties are needed as well. Which one is not correct immunogenic properties?

#Unit 4. Cell Communication and Cell Signaling
  1. synthetic homopolymers  (polymers composed of a single amino acid or sugar) tend to lack immunogenicity regardless of their size.
  2. that copolymers composed of different amino acids or sugars are usually more immunogenic than homopolymers of their constituents.
  3. greater the phylogenetic distance between two species causes lower immunogenic 
  4. bovine serum albumin (BSA) is not immunogenic when injected into a cow but is strongly immunogenic when injected into a rabbit.
