Which of the following is incorrect statement 

#Unit 2. Cellular Organization
  1. H32-H42 tetramer accounts for the diameter of the octamer.
  2. The H32-H42 tetramer alone can organize DNA
  3. H32-H42 tetramer show a similar type of structure in which three a-helices are connected by two loops. This highly conserved structure is called the histone fold
  4. Each histone also has a flexible N-terminal tail but H2A and H2B have also have C-terminal tails for covalent modification.
