Sequencing

 Determination of nucleotide sequence in DNA is the important technique in molecular biology.  This technique was first developed by the two scientist groups in 1975.  Maxam AM and Gilbert W. American scientists at Havard University developed the nucleotide sequencing technique using the chemical method.  Sanger F, Niklen S and Coulson AR, the Bristish scientists at Cambridge successfully developed this technique using the enzymatic method.  Nowadays these techniques are widely used in molecular biology research.  The strategies for DNA sequencing consists of 4 steps: 1. Preparation of DNA template 2. Sequencing reaction 3. Electrophoresis 4. Analysis 1. Preparation of DNA template The DNA template used for sequencing can be prepared by several methods: a) Gene cloning It is conventional method.  Isolate and purify genomic DNA.  Cut with appropriate restriction enzyme.  Cut sequencing vector with the same enzyme.  Insert DNA ...
