Which of the following is incorrect about molecular diagnostics?

Molecular diagnostics uses PCR for pathogen detection.
Molecular diagnostics is used for identifying genetic mutations.
Molecular diagnostics relies solely on light microscopy.
Molecular diagnostics helps in early disease detection.
3

Molecular diagnostics does not rely solely on light microscopy; it uses advanced techniques like PCR and hybridization for accurate detection.

Which of the following is correct about somatic hybridization?

Somatic hybridization involves fusion of protoplasts from different species.
Somatic hybridization is a method of sexual reproduction.
Somatic hybridization produces genetically identical clones.
Somatic hybridization is unrelated to plant biotechnology.
1

Somatic hybridization involves the fusion of protoplasts from different plant species to form hybrid plants with combined traits.

Which of the following is incorrect about biopiracy?

Biopiracy refers to unauthorized use of biological resources.
Biopiracy promotes fair trade of biological materials.
Biopiracy is regulated by biodiversity laws.
Biopiracy often leads to exploitation of indigenous knowledge.
2

Biopiracy involves unauthorized exploitation of biological resources and does not promote fair trade.

Which component in PCR initiates the DNA synthesis process?

DNA polymerase
Primers
dNTPs
Template DNA
2

Primers bind to specific sequences and initiate DNA synthesis in the PCR process.

Which disease was the first to be treated using gene therapy?

Adenosine deaminase deficiency
Sickle cell anemia
Hemophilia
2

Adenosine deaminase (ADA) deficiency was the first disease to be treated using gene therapy.

Which term describes the ability of a single plant cell to grow into a whole plant?

Pluripotency
Totipotency
Multipotency
Omnipotency
2

Totipotency is the ability of a single plant cell to regenerate into a whole plant under suitable conditions.

Which term describes the fusion of two protoplasts from different species to form a hybrid?

Hybridization
Somatic hybridization
Transgenesis
Cloning
2

Somatic hybridization involves the fusion of protoplasts from different plant species to form a hybrid.

Which protein produced by Bacillus thuringiensis is toxic to insects?

Cry protein
Bt enzyme
Protease
Ligase
1

Cry protein produced by Bacillus thuringiensis is toxic to insect larvae and is used in pest-resistant crops.

Which of the following statements is correct about gene cloning?

Gene cloning is used to destroy genes in organisms.
Gene cloning involves inserting a gene of interest into a host organism for replication.
Gene cloning is unrelated to recombinant DNA technology.
Gene cloning does not involve vectors.
2

Gene cloning involves inserting a gene of interest into a host organism using vectors to produce multiple copies of the gene.

Which of the following is a critical area of biotechnology research?

Traditional breeding
Downstream processing technologies
Organic farming
