WebFeb 2, 2010 · Rather, the Cry2 trp mutation may have caused a nonspecific effect on magnetosensing function due to protein misfolding. Thus, Cry2 may use a photochemical mechanism common to both Type 1 and Type 2 Cry, such as the photolyase-like photocycle mentioned above. WebIn attempts to test the nature of these magnetite structures, experiments were devised to determine whether disrupting their magnetic polarity would affect the magnetoreception ability of the organism. The conclusion drawn was that the magnetite structures could play the role of some form of magnetic map, built up over time. how big is a 23 ounce cheesecake
