Newsbrief: CBSE Releases Class 12 Biotechnology Sample Paper for 2025-2026
The Central Board of Secondary Education (CBSE) has released the latest sample paper for Class 12 Biotechnology for the school year 2025-2026. This paper is designed to help students study and prepare for their upcoming tests.
The paper consists of five sections, each focusing on different aspects of Biotechnology. Here's a breakdown of the sections:
Section A: This section contains 12 multiple choice questions (1 mark each) and 4 assertion-reasoning questions (1 mark each). Questions range from identifying the cause of severe combined immunodeficiency disease to calculating the mass to charge ratio of a protein ion.
Section B: This section has 5 short answer questions, each worth 2 marks. Topics include primary cell culture, secondary metabolites produced by microbial cells, and the differences between homologues and paralogs.
Section C: This section consists of 7 short answer questions, each worth 3 marks. Topics include the relationship between the number of genes and proteins, the location of single nucleotide polymorphisms, and the gene contained in YEp that codes for a specific protein.
Section D: This section has two case-based questions, each worth 4 marks. These questions require students to apply their understanding of Biotechnology concepts to real-world scenarios.
Section E: This section has three long answer questions, each worth 5 marks. These questions require students to delve deeper into topics such as genetic engineering, recombinant DNA technology, and biotechnology in agriculture.
The paper is compulsory, with some internal choices provided in certain questions. Students must attempt only one of the alternatives in such questions. The marking scheme allocates a total of 70 marks, with the detailed answers and distribution per question available in the official CBSE marking scheme PDF for Biotechnology 2025-26.
The paper also serves as a practice test for students, helping them understand the question type and overall mark weighting. Students are advised to draw neat and properly labeled diagrams wherever necessary. The sample paper, along with the grading scheme, can be downloaded for free.
With the release of this sample paper, students can now start preparing for their Class 12 Biotechnology exams with a clear understanding of the type of questions that may be asked. Good luck to all the students!
Engaging in online education platforms can supplement a student's education-and-self-development, providingan opportunity to learn about Biotechnology concepts beyond the class curriculum. For instance, one can find practical problems similar to those in the recently released CBSE Class 12 Biotechnology sample paper for 2025-2026, aiding in the preparation of the upcoming tests through online learning.
