the technique used to separate charged molecules on the basis of size and charge is:
isolation of dna
gel electrophoresis
molecular separation
nucleic acid fragmentation

Explanation:

Gel electrophoresis is a laboratory technique used to separate charged molecules (such as DNA, RNA, or proteins) based on their size and charge. A gel (usually agarose or polyacrylamide) is placed in an electric field. Charged molecules move through the gel: smaller molecules move faster and farther than larger ones. Isolation of DNA is a process to obtain DNA from cells, not a separation - based - on - size - and - charge technique. Molecular separation is a very general term and not a specific technique like gel electrophoresis. Nucleic acid fragmentation is about breaking nucleic acids into smaller pieces, not separation based on size and charge.

Answer:

gel electrophoresis
