what is gel electrophoresis?
○ a) a technique in which dna samples are cut by restriction enzymes, and the resulting fragments are separated via electrophoresis creating a pattern of bands.
○ b) a process used to separate fragments based on charge and size.
○ c) a process in which the size and order of dna segments is determined.
○ d) the technique of quickly making copies of dna using enzymes and a cyclic fluctuation in temperature

Explanation:

Gel electrophoresis is a technique in molecular biology. DNA samples are cut by restriction enzymes. Then, the resulting fragments are separated via electrophoresis. The separation is based on the charge (DNA is negatively - charged and moves towards the positive electrode) and size (smaller fragments move faster) of the DNA fragments, creating a pattern of bands.

Answer:

a) A technique in which DNA samples are cut by restriction enzymes, and the resulting fragments are separated via electrophoresis creating a pattern of bands.
