GAT-B 2023 Syllabus: Complete Guide for Biotechnology PG Program Admission

Updated On - May 08 2023 by Abhinandan Singh

The Graduate Aptitude Test-Biotechnology (GAT-B) 2023 is conducted for admission in various DBT supported PG programs in Biotechnology and allied areas. The GAT-B 2023 exam is conducted at the national level annually by the National Testing Agency (NTA). The GAT-B 2023 Syllabus includes topics such as Molecular Biology and Genetics, Recombinant DNA Technology, Immunology, Biochemistry, Bioinformatics, etc. The syllabus is designed to test the conceptual understanding and knowledge of candidates in the field of Biotechnology. Candidates must thoroughly prepare for the exam as it is highly competitive and admission to PG programs is based on GAT-B scores.

CategoryTopics Covered in GAT-B 2023 Exam
GeneralMathematics, Aptitude, General Biotechnology
Core BiotechMicrobiology, Biochemistry, Molecular Biology, etc.
The GAT-B 2023 exam syllabus covers a wide range of topics related to biotechnology, including general biotechnology, mathematics, aptitude, microbiology, biochemistry, and molecular biology. The exam is divided into two categories: general and core biotechnology. The general category focuses on fundamental concepts and principles, while the core biotechnology category delves deeper into specific subjects such as microbiology and biochemistry. Candidates should thoroughly review the syllabus before beginning their exam preparation to ensure that they cover all of the necessary topics. The GAT-B exam is a computer-based test that lasts for three hours and is held for admission to postgraduate programs in biotechnology and allied areas at participating institutions.
