Question

question 33
during ____, dna fragments are separated based upon size
○ electrophoresis
○ polymerase chain reaction
○ electrocution
○ molecular cloning

Explanation:

Electrophoresis is a technique used to separate DNA fragments based on their size. Smaller fragments move faster through the gel matrix compared to larger ones. Molecular cloning is about inserting DNA into vectors. Electrocution is a method of cell - membrane permeabilization. Polymerase chain reaction is for amplifying DNA.

Answer:

Electrophoresis
