DNA fingerprinting

• The technology of testing the arrangement of nucleotides is called DNAprofiling.
• DNA profiling is also called DNA fingerprinting since the arrangement of nucleotides differs from person to person like the difference in the fingerprints of each person.
• Due to this reason, this technique can be used to identify the culprit in case of murder, robbery etc.
