Verified step by step guidance

Understand the concept of dialysis: Dialysis is a process that separates molecules in solution based on their size using a semi-permeable membrane.

Recognize that in dialysis, smaller molecules and ions can pass through the membrane, while larger molecules are retained.

Identify the purpose of dialysis in biochemistry: It is often used to remove small unwanted molecules from macromolecules like proteins or nucleic acids.

Differentiate dialysis from other techniques: Unlike gel electrophoresis, which separates molecules based on charge and size, dialysis focuses solely on size exclusion.

Conclude that among the given options, dialysis is the procedure that uses membrane bags to separate molecules based on molecular size.
