<span>An electric current is running through the gel in the electrophoresis with positive pole on the bottom. So, only negatively charged particles can migrate through the gel in the electrophoresis. </span>Since DNA is negatively charged, it migrates toward the positive pole of the gel. This characteristic enables DNA to move through the gel.
Its A
110 400
235 x
Then cross multiply.... 110 times x = 110x
400 x 235 = 94000
then all that's left is to divide.
94000/110 :) = 854.46
