Detailed explanation-1: -[Editors note: DNA fingerprinting uses gel electrophoresis to distinguish between samples of the genetic material.
Detailed explanation-2: -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.
Detailed explanation-3: -After the DNA has been digested with one or more restriction enzymes, it is separated by size using gel electrophoresis. A radioactive probe is then used to identify certain fragments of DNA that may differ between individuals.
Detailed explanation-4: -Therefore, the option that best describes what is meant by DNA fingerprinting is given by answer choice (C). DNA fingerprinting is a technique that analyses the patterns produced by unique repetitive DNA sequences in the genome of an individual.
