Concept explainers
Interpretation:
The lane representing an identical twin of the individual whose DNA is shown in lane 1 should be determined.
Concept Introduction:
DNA of each individual is unique. Only identical twins have identical DNA. Individuals who are blood related may have similar DNA fragments. DNA fingerprinting is a technique used to identify an individual by comparing his/her DNA with another DNA sample. First DNA sample is amplified and then they are cut by several restriction enzymes. The resulting fragments are then separated based on size by gel electrophoresis. The separated DNA fragments are visualized by staining, radioactive probe or using X-ray. Individuals can be identified by comparing the DNA band patterns generated by gel electrophoresis. Related DNA samples have similar DNA patterns.
