GATE Biotech Important Topics – Unit Wise & Reference Books

GATE is an examination conducted jointly by the IISc, Bangalore and seven IITs on behalf of the National Coordination Board (NCB)-GATE. Candidates have the option of selecting only one GATE paper for examination. The scorecard signifies the relative performance level of the candidate in a particular subject (quantified based on several years of examination data).GATE exam score is valid for 3 years from the announcement date of the results.

IIT, Delhi is the conducting authority of the GATE 2020 examination.

GATE qualification is beneficial for students seeking admission and/or financial assistance for either a Master’s program and direct Doctoral programs in Technology/Engineering/Architecture or to Ph.D. programs in relevant branches of Science (in some institutions supported by the MHRD and other Government agencies). GATE qualification is even mandatory in some colleges and institutions, which admit students without MHRD scholarship/assistantship. Additionally, many Public Sector Undertakings (PSUs) ask for the GATE score in their recruitment process.

Biotechnology is one of the most trending fields for research in our era. There are innumerable applications of Biotechnology in health care, agriculture, pharmaceuticals, industry which are vast and critical. Having said so, GATE preparation for Biotechnology (BT) paper demands the students to have the best knowledge of the concepts.

So in case, you feel you have no idea about where to start, or what to refer, here is a list of – GATE Biotech Important Topics – Unit Wise & Reference Books. Books required for all topics covered in GATE syllabus along with the important subtopics are listed below:

SECTION 1: Engineering Mathematics

GATE Biotech Important Topics from Engineering Mathematics. The Engineering Mathematics of GATE BT paper carries around 15% of the total marks, the General Aptitude section another 15% of the total marks. The remaining 70% of the total marks are allotted for questions from the core subject of the paper. These 30% marks are extremely important to decide on one’s rank and score. One may think that they can easily score in subject questions, but questions can be unexpected and there are always few NAT questions that are confusing. So it will be a wise decision to prepare both very well (GA+ mathematics as well as subject concepts).

General Aptitude intends to test the Language (2 marks) and Analytical Skills (13 marks). Mainly questions are from data interpretation, volume, area, surface area, perimeter, speed, chain rule, logarithm, probability, mixture, ratio, fraction, permutation and combination, etc. On analyzing GATE Biotechnology question papers for the last 4–5 years, we have noticed that some topics are more commonly asked than others such as Matrices, Determinants, and Differentiation, etc. hence one can focus on these topics to score well.

SECTIONS ON CORE SUBJECT:

The trend of the questions in the previous papers of GATE BT sees a major share of questions from Biochemistry and Bioprocess Engineering. 35–40 marks are set from these two portions out of the 70 marks based on the Biotechnology subject. Extra attention and special emphasis should be put on Bioprocess since the share of numerical questions have seen a marked increase in the last few years. Hence, needless to say, bioprocess engineering numerical is the most crucial. Mass transfer, bacterial kinetics, scale-up of fermentation are significant topics. Biochemistry questions are mostly based on enzyme kinetics, pathways, and bioenergetics. Each of the other subjects such as cell and molecular biology, microbiology, immunology, rDNA technology, bioinformatics have almost an equal share of marks not exceeding 10maks in each. If one can maximize the marks in these two areas, a below 50 AIR can be achieved.
