A) The dots permit the position of the proteins to be determined more precisely.
B) The dots permit the average distance between the proteins to be determined more precisely.
C) The dots permit the size of the proteins to be determined more precisely.
D) The dots permit the motion of the proteins to be determined more precisely.
E) The dots permit visualization of proteins interacting with lipids.
