Variants of PCR has been devised for mutational analysis AS-PCR, Site-directed-mutagenesis (Oligonucleotide-directed Mutagenesis), overlap extension PCR, Megaprimer PCR.
#Id: 874
Touchdown PCR, has been devised to increase the specificity of PCR without lowering the efficiency by variation annealing temperature.
#Id: 875
HOT START PCR were devised to prevent non – specific amplification at low temperature.
#Id: 876
FRET is possible only when the distance between donor and acceptor are within 1 to 10 Å
#Id: 877
GFP chromophore comprises an oxidized form of the tripeptide –Ser65–Tyr66–Gly67–.
#Id: 878
The efficiency of FRET is inversely proportional to the sixth power of the distance between donor and acceptor.
