What is AFLP technique?
Amplified fragment length polymorphism (AFLP) is a PCR-based technique that uses selective amplification of a subset of digested DNA fragments to generate and compare unique fingerprints for genomes of interest.
What does Taq polymerase do in PCR?
“The function of Taq DNA polymerase in PCR is to amplify or synthesize DNA or gene of interest for various downstream applications. It’s a type of thermostable DNA polymerase, work at a higher temperature as well.”
What are dNTPs used for?
The dNTPs are the artificial nucleotides used in the PCR to synthesize new DNA strands much like DNA replication. dATP, dTTP, dGTP, dTTP are common nucleotides present in the PCR mastermix.
What is rNTP in biology?
From Wikipedia, the free encyclopedia. A ribonucleoside tri-phosphate (rNTP) is composed of a ribose sugar, 3 phosphate groups attached via diester bonds to the 5′ oxygen on the ribose and a nitrogenous base attached to the 1′ carbon on the ribose.
Are there any ways to recover DNA from fingerprints?
So far we have successfully recovered DNA and fingermarks on several surfaces that are likely to be encountered at crime scenes, including textured plastics and paper, with no statistically significant differences in the quality of the marks.
How to test your knowledge of DNA fingerprinting?
To get a complete understanding of DNA fingerprinting, keep visiting BYJU’S website or download BYJU’S for further reference. Test your Knowledge on DNA Fingerprinting! Put your understanding of this concept to test by answering a few MCQs.
How is DNA fingerprinting used to trace evolution?
In case of the change in gene frequency or genetic drift, Fingerprinting can be used to trace the role of this change in evolution. To get a complete understanding of DNA fingerprinting, keep visiting BYJU’S website or download BYJU’S for further reference. Test your Knowledge on DNA Fingerprinting!
Can a fingerprint be used to identify someone?
Fingerprints hold a lot more information than you might realise. They don’t just provide a pattern with which to identify people. They can also contain DNA. And as neither DNA nor fingerprints are infallible ways of working out who was at a location, combining both pieces of evidence could be vital for investigators.
