Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
Solution:
The genetic material dna consists of basic subunits called Nucleotides.
Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine.
