DNA Fingerprinting Definition, Process, Analysis

Today our topic is DNA Fingerprinting. Which is the technology to identify the criminal etc. It is the best technology in the biological field. All countries use this technology. Hope you will enjoy to read this and gather all information. Please share your reviews in comment. DNA fingerprinting was discovered by the Professor Alec Jeffreys in 1984. Every person have unique DNA fingerprint.

What is DNA?

DNA is the abbreviation of deoxyribose nucleic acid. It is the component of our all cells and control the whole cell. It is the Major component of the cell.

DNA Fingerprinting Definition

DNA Fingerprinting is a technique in which by comparing the fingerprint of different person, a criminal or detector can be identify on biological evidence. It is the laboratory technique which is used in the biological field.

DNA Fingerprinting Process

For creating the DNA fingerprint we need a sample of cell, blood, skin hair etc.

DNA fingerprinting is consists of many step which are given below DNA fingerprinting process starts when DNA from anybody like as blood, teeth, hair, bones etc. separated. Then take many copies of this DNA for procedure. Then enter one part of enzyme in DNA. Then treat DNA with radioactive substance for detection. It will chip with the DNA then take x-ray of it.

Here are all steps of DNA fingerprinting Process

  • Extracting DNA from Cells. To perform DNA fingerprinting, you must first have a DNA sample! …
  • PCR Amplification (Optional)
  • Treatment with Restriction Enzymes
  • Gel Electrophoresis
  • Transfer onto Southern Blot
  • Treatment with Radioactive Probe
  • X-Ray Film Exposure

Here is a video where you can watch all the process and analysis of DNA fingerprint.
