Scientific information refers to the classification, collection, dissemination, and retrieval of recorded knowledge treated both as a pure and as an applied science. The two features of a scientific information source, which may suggest that the information is not reliable are:
1. The information is based on data that are not peer-reviewed, that is, the information has not been reviewed by the experts in the field, or is not encouraged by an accord of experts in the field.
2. The references are not cited, that is, it not clear or not known that from where the information originated.
For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.
