Question

What did Alec Jeffrey use as a probe while developing the DNA Fingerprinting technique?

Answer 1

DNA fingerprinting:

1. It is a molecular technique that detects unique patterns in the DNA code of an individual and provides genetic data that is unique.
2. Alec Jeffrey discovered genetic fingerprinting and DNA profiling techniques.

Probes:

1. These are usually single-stranded labeled DNA strands whose DNA sequences are known.
2. They are used to search for its complementary sequence in a sample genome.
3. DNA strand consisting of short sequence but huge number times is known as Satellite DNA.
4. Such satellite DNA is used as a probe by Alec Jeffrey in DNA finger printing which shows a high degree of polymorphism. This means that a particular DNA segment shows variation from one individual to another.
