CBSE class 12 biotechnology deleted syllabus 2023-24 includes chapters like Recombinant DNA technology hybridization techniques, Protein structure and Engineering 3-D shape of proteins, Genomics and more.
The CBSE class 12 biotechnology deleted syllabus 2023-24 includes chapters like Recombinant DNA technology hybridization techniques, Protein structure and Engineering 3-D shape of proteins, Genomics, Proteomics and Bioinformatics, etc. The CBSE class 12th syllabus is restructured by deleting portions from two units. Therefore students must prepare for the biotechnology syllabus of 70 marks by considering the revised syllabus.
The board has released the CBSE class 12 syllabus for the academic year 2023-24. With the restructuring of the syllabus through CBSE class 12 biotechnology deleted syllabus 2023-24, the entire weightage and marks distribution has been affected. Therefore, candidates must acquaint themselves with these new pattern syllabi.

CBSE Class 12 Biotechnology Deleted Syllabus 2023-24 for Practicals
The board has also eliminated some practical topics for the academic year 2023-24. The Biotechnology practical examination has 30 marks, and students must thoroughly understand the topics to score higher. Some of the deleted topics are:
- Isolation o genomic DNA (CTAB method)
- Bacterial transformation using any plasmid
- Restriction digestion of plasmid DNA&its analysis by gel electrophoresis
Reasons for CBSE Class 12 Biotechnology Deleted Syllabus 2023-24
The CBSE authorities have decided to restructure the CBSE class 12 syllabus as part of the CBSE class 12 biotechnology deleted syllabus 2023-24. Some of the valid reasons for the CBSE class 12 biotechnology deleted syllabus 2023-24 are:
- Restructuring the CBSE class 12 biotechnology syllabus will impart a self-learning culture.
- By restructuring the syllabus, the board will strengthen the foundational topics and focus on simpler ones.
- Students can score higher marks by following the revised structure.
Benefits of CBSE Class 12 Biotechnology Deleted Syllabus 2023-24
Besides making the syllabus structure simple by reducing the CBSE class 12 Biotechnology syllabus, there are many advantages students must note.
- The restructured syllabus is more flexible, allowing candidates to focus only on concise and simple concepts.
- With the CBSE class 12 biotechnology deleted syllabus 2023-24, students can focus more on the important topics, which leads to better productivity.
- Students can check the weightage system and can plan their studies accordingly.
