How is CHSE Odisha Higher Secondary Elective Biotechnology examined?

Biotechnology is a Science stream Group-B 4th elective under CHSE Odisha. Each year carries 100 marks. Year-1 college assessment covers Units I–IV theory (70 marks in science_2016) plus practical (30). Year-2 Council AHSE covers Protein and Gene Manipulation (40) and Cell Culture and Genetic Manipulation (30) for theory, with practical assessment per the current circular. The Council Year-2 result contributes to the pass certificate.

What does Year 1 Biotechnology cover?

Class XI covers Unit I Biotechnology overview (history, production strategies, QC, GMP/GLP, IP, markets), Unit II Molecules of Life (biomolecules and macromolecules), Unit III Genes & Genomes, and Unit IV Cells and Organisms, plus practicals such as buffers/pH, sterilisation, bacterial media and growth, mitosis, karyotyping, cell counting, and genomic DNA isolation.

What does Year 2 Biotechnology cover?

Class XII Unit V Protein and Gene Manipulation includes recombinant DNA technology, protein structure and engineering, and genomics/bioinformatics. Unit VI Cell Culture and Genetic Manipulation covers microbial, plant, and animal cell culture techniques, applications, stem cells/tissue engineering, and biosafety themes.

Is this practice bank the same format as the official CHSE paper?

No. Official papers mix objective and constructed-response theory with practical skills. This bank is an English-language multiple-choice study adaptation for concept revision—not an official blueprint replica or lab substitute.

What is the pass mark?

CHSE Odisha AHSE practice commonly requires about 30% as a minimum pass floor in theory for Higher Secondary subjects; practical subjects also require satisfactory practical performance. Confirm the current AHSE notification on chseodisha.nic.in.

What does the exam cost?

Examination charges are included in the CHSE Odisha AHSE fee structure notified for the session and collected through the affiliated college/H.S. school—no separate public per-elective marketplace fee.

Sample CHSE Odisha Elective Biotechnology Practice Questions

Try these sample questions to test your CHSE Odisha Elective Biotechnology exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to the CHSE +2 Biotechnology overview unit, biotechnology is best described as:

A.The use of living systems and organisms to develop products and processes for human use

B.Only the chemical synthesis of plastics from petroleum

C.Only astronomy-based mapping of stars

D.Only pure theoretical mathematics without applications

Explanation: Biotechnology applies biological systems, cells, and biomolecules to make useful products and processes—central to the syllabus overview of production strategies and applications.

2Good Manufacturing Practices (GMP) in biotechnology primarily ensure:

A.Consistent production quality and control of manufacturing conditions for product safety

B.That only one scientist ever enters a laboratory

C.That patents are never filed

D.That fermentation vessels are never cleaned

Explanation: GMP are quality systems ensuring products are consistently produced and controlled according to quality standards—paired in the syllabus with product safety and QC.

3Good Laboratory Practices (GLP) mainly concern:

A.Standardised planning, performance, monitoring, recording, and reporting of non-clinical laboratory studies

B.Only marketing slogans for biotech companies

C.Only classroom seating arrangements

D.Only stock-market listing rules

Explanation: GLP framework quality and integrity of laboratory study data—listed alongside GMP and QC in Unit I overview.

4Intellectual property protection for a novel recombinant therapeutic protein is most directly associated with:

A.Patents that grant time-limited exclusive rights in exchange for disclosure

B.A permanent ban on all scientific publication

C.Mandatory secrecy forever with no filing system

D.Only trademarks on laboratory furniture brands

Explanation: The overview unit lists intellectual property; patents are the main tool protecting inventive biotech products/processes for limited terms.

5A key public-perception issue for modern biotechnology is often:

A.Societal acceptance of GMOs, biosafety, and ethical use of genetic technologies

B.Whether gravity exists

C.Whether water freezes at 0 °C under standard conditions

D.Whether DNA contains nucleotides

Explanation: Unit I lists public perception alongside product safety; debates on GMOs, ethics, and risk communication are classic biotech social issues.

6Production strategies in industrial biotechnology commonly emphasise:

A.Selecting suitable organisms/hosts, optimising processes, and ensuring quality and safety of outputs

B.Ignoring yield and only maximising random mutations without screening

C.Eliminating all quality checks to save time

D.Using only non-sterile open sewers as bioreactors by design

Explanation: Syllabus production strategies pair strain/process design with quality control and product safety for commercial biotech.

7Metagenomics applied to microbial technology is best described as:

A.Studying genetic material recovered directly from environmental samples without culturing every organism

B.Only Gram staining a pure plate culture

C.Only counting yeast cells in a haemocytometer

D.Only autoclaving media

Explanation: Metagenomics expands access to uncultured microbial diversity for discovery—linked to modern microbial culture/application themes.

8Product safety evaluation for a biotech therapeutic typically requires:

A.Quality control testing, documented manufacturing controls, and regulatory compliance pathways

B.No testing if the product looks clear

C.Only a single unrecorded experiment by one person

D.Skipping batch records entirely

Explanation: Overview links product safety with QC, GMP, and controlled production—core exam themes for industrial biotech context.

9The monomeric building blocks of proteins are:

A.Amino acids

B.Monosaccharides only

C.Nucleotides only

D.Fatty acids only

Explanation: Proteins are polymers of amino acids linked by peptide bonds—Unit II building blocks.

10Which functional groups characterise a standard α-amino acid used in proteins?

A.An amino group and a carboxyl group attached to the same α-carbon (plus an R side chain)

B.Only a phosphate and a deoxyribose with no nitrogen

C.Only long hydrocarbon chains without heteroatoms

D.Only metal ions with no carbon backbone

Explanation: α-Amino acids have –NH2 and –COOH on the α-carbon with variable R groups that determine properties.
