CBSE Class 12 Biotechnology exam scheduled for March 21

The CBSE Class 12 Biotechnology exam is set for March 21, 2025. Students are advised to prepare by reviewing important questions available on the CBSE's official website. Some key topics for preparation include the dideoxynucleotide chain termination method and its inventor. Students should also understand why the dye termination method is preferred and how autoradiograms are read from bottom to top. Other important areas include the role of restriction enzymes produced by bacteria and the basic steps involved in plant tissue culture. Students should be familiar with techniques for making intergeneric somatic hybrids and the concept of cybrids. Additionally, it's important to know the advantages of edible vaccines over recombinant vaccines and how to calculate the m/z ratio in mass spectrometry. Doctors may need to consider specific parameters when recommending protein-rich diets for athletes. In genetic engineering, students should understand selection techniques using antibiotics like ampicillin and tetracycline to differentiate between recombinant and non-recombinant cells. Finally, the implications of gene cloning and the charge relay system in chymotrypsin are also key concepts that students need to grasp.
