What is DNA fingerprinting or DNA profiling?
Leicester University geneticist Alec Jeffreys developed a technique called DNA fingerprinting in 1985. It allows DNA samples from different people to be compared to look for similarities and differences. It is useful for solving crimes and can also confirm if people are related to each other, like in paternity testing. Any two people in the world have 99.9% of their DNA the same, so this process analyses the differences in the remaining 0.1%.
This modern technology is called DNA profiling.

Textbooks(NCERT) lines were boring and tough to understand but you have made them easy with this video... Thank you very much
Exactly what I was looking for. No dry lecture, just a short, perky little video - thanks.
This explanation conflates two different techniques. The old method of DNA fingerprinting used restriction enzymes. The new method uses PCR. The old method requires a lot of DNA, the new method does not. Once an individual's STR's are amplified enough to see on a gel, you run the DNA directly - no cutting it up or you will skew your results! If you look at enough STR's (~13) the probability that two individuals would have all 13 STR's be the same length is small enough to distinguish among 7 billion people. You guys put out really good stuff, but I can't share this with my students as it is! Would love to see another version, because your graphics and pacing are really good.

When he said Loci.. The first thing that came to my mind was Loki
I am tejas Nagarkar I understand lecture
After reading in my book, I thought it's so much difficult. Now it's very much easy after watching this video. Thank you so much for this video 😊😊😊
I was looking for a proper video of DNA test . And found here one.Thanks a bunch . Love from Bangladesh
Thank you for telling me. Now i will become bald were gloves and after the crime i will change my identity with help of plastic surgery
Might be a dumb question but what is a Rios?
Steps of Dna Fingerprinting:-
Crisp yet lucid explanation! Thank you for this one!👍👍
Exactly what i need for a quick revision a night before the exam.
That was extremely helpful, thank you so much !
Thank you so much! It has helped greatly because I have to answer some questions on this
Fuse school is the best educational channel .. hope u r not running in a loss for putting this much of ur effort and animations
thank you so much! I have been studying this for half an hour and i still had not understood. Thanks to this amazing and simple explanation I finally got it.
Really such a great video !! All concepts explained so nicely !! Thank you !!!!
Fuse school always helps me to take my understanding of the topics while studying to the next level.
Thank you so much. All concept in just 4 minutes.😍
