DNA FINGERPRINTING..

Introduction of DNA Fingerprinting,DNA Profiling,It’s Steps !!

DNA FINGERPRINTING DNA fingerprinting is a method of identification that compares fragments of DNA with the exception of identical siblings; the DNA of each person is unique. Process of DNA finger printing was invented by Alec Jeffreys in 1985. It is a method for identifying individual by their unique pattern of DNA banding STEPS OF […]

DNA SEQUENCING

DNA sequencing,Sanger sequencing,Illumina Sequencing !!

DNA SEQUENCING                         DNA sequencing is a process of determining the precise order of nucleotides within a DNA molecule. It includes any technology that is used to determine the order of the four bases. Adenine (A) Guanine (G) Cytosine(C) Thymine (T) Sequencing is a complex method. It requires breaking the DNA of the genome into many […]

Polymerase Chain Reaction,PCR !!

PCR In 1980s, an important revolutionary technique of molecular biology PCR or Polymerase chain reaction was first described. Kary Mullis has been awarded for PCR in 1993. PCR takes place without living cells in the tube with the help of special heat stable DNA polymerase enzyme. Here the primer strand in the form of oligonucleotides […]
