a) Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules.
b) Brownian motion is the random motion of a particle as a result of collisions with surrounding gaseous molecules. Diffusiophoresis is the movement of a group of particles induced by a concentration gradient. This movement always flows from areas of high concentration to areas of low concentration.
c) The process of becoming viscous or thickened into a coherent mass : the forming of clots (as in blood or cream) : the process of coagulating an incision is made on the skin of the forearm with a spring-loaded device, and the time to coagulation is measured.
