#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.

Which of the following given facts regarding CAM Plants are TRUE?

a.) The leaves of CAM plants have traits that minimize water loss, such as thick cuticles, large vacuoles, and stomata with small apertures

b.) All CAM plants, the initial capture of CO2 into four-carbon acids takes place at night, and the posterior incorporation of CO2 into carbon skeletons occurs during the day
