AB Viruses  range  from  20  to  300  nm  in  diameter;  this  corresponds  roughly  to  a  range  of  sizes  from  that  of  the  largest  protein  to  that  of  the  smallest  cell  (see  Figure  2–2).  Their  shapes  are  frequently  referred  to  in  colloquial  terms  (e.g.,  spheres,  rods,  bullets,  or  bricks),  but  in  reality,  they  are  complex  structures  of  precise  geometric  symmetry  (see  later).  The  shape  of  virus  particles  is  determined  by  the  arrangement  of  the  repeating  subunits  that  form  the  protein  coat  (capsid)  of  the  virus.  The  shapes  and  sizes  of  some  important  viruses  are  depicted  in  Figure  28–1.
