A demo of techniques used in Biotechnology was done by Dr Tripti Bhatnagar of Biotechnology Company, Codon Biotech for Class XII Biotechnology students on 17 November 2017. The students learnt the method to isolate plasmid DNA from the bacteria, E.coli and performed Agarose Gel Electrophoresis. They carried out restriction digestion and saw fluorescent DNA fragments under Transilluminator. Students did quantitative Spectrophotometric Analysis of DNA and Protein. Ms Niva Chhonkar, Coordinator- Biology elaborated the precautions to be taken while performing these experiments. Students from Biologxy sections were excited to see the DNA fragments separated during electrophoresis.
