Q4

Drought resistance in plants is an example of protection against which type of stress?

  • A) Viral stress
  • B) Nutritional stress
  • C) Biotic stress

Q5

What happens to the cell membrane during electroporation?

  • A) It forms a thick wall around the cell
  • B) It is completely destroyed
  • C) Transient, nanometer-sized pores are generated
  • D) It becomes permanently permeable
AI Explanation
Electroporation applies an electric field that temporarily disrupts the lipid bilayer of the cell membrane. This creates transient nanometer-sized pores through which DNA or other molecules can enter the cell.

Q6

Which was the first human therapeutic protein to be expressed in genetically modified plants?

  • A) Interferon
  • B) Human serum albumin
  • C) Insulin
  • D) Growth hormone
AI Explanation
Interferon was among the earliest human therapeutic proteins successfully expressed in genetically modified plants. Plant-based expression systems can produce recombinant human proteins for pharmaceutical applications.

Q7

Why is transfection with polyplexes considered more efficient than some other chemical methods?

  • A) Because they do not require any cells
  • B) Because they work only in plant cells
  • C) Because they have a uniform particle size
  • D) Because they are cheaper to produce
AI Explanation
Polyplexes are complexes formed between nucleic acids and positively charged polymers. Their relatively uniform particle characteristics can improve cellular uptake and make transfection more efficient than some other chemical approaches.

Q8

Which trait is the most widespread in commercial transgenic plants?

  • A) Drought tolerance
  • B) Herbicide resistance
  • C) Insect resistance
  • D) Salt tolerance
AI Explanation
Herbicide resistance is one of the most widely adopted traits in commercial transgenic crops. It allows crops to tolerate specific herbicides while weeds are controlled.

Q9

Protoplast transformation is highly efficient for DNA uptake but can be limiting for generating whole transgenic plants. What is a major downstream challenge after successfully transforming a protoplast?

  • A) It is difficult to regenerate an entire fertile plant from a single protoplast.
  • B) The protoplasts are immediately resistant to antibiotics.
  • C) Protoplasts cannot express foreign genes.
  • D) The transformation is only transient.
AI Explanation
Although protoplasts can efficiently take up foreign DNA, successful transformation is only an early step. A major challenge is regenerating the transformed protoplast into a complete, fertile plant through cell division and tissue regeneration.

Q10

A biotechnology company needs a homogeneous population of single plant cells for high-throughput screening of a new herbicide. They start with a solid callus culture. What should be their next critical step to achieve this?

  • A) Induce somatic embryogenesis in the callus.
  • B) Subject the callus to cryopreservation.
  • C) Treat the callus with a cell wall-digesting enzyme.
  • D) Transfer the callus to a liquid medium and agitate it on a shaker.

Q14

In an experiment, a researcher creates a nutrient medium containing only a high concentration of auxins to initiate callus from leaf explants. The callus forms but quickly begins to differentiate into roots. What is the most likely explanation?

  • A) The explant was contaminated.
  • B) The sugar concentration was too low.
  • C) The balance of hormones was incorrect; cytokinins were needed to suppress differentiation.
  • D) The temperature was too high.

Q15

When was the expression of foreign genes in plants first successfully achieved?

  • A) Mid-1990s
  • B) Early 2000s
  • C) Early 1980s
  • D) Late 1970s
AI Explanation
The first successful expression of foreign genes in plants was achieved in the early 1980s using recombinant DNA and plant transformation techniques. This established the foundation for modern plant genetic engineering.

Q16

What is essential in the nutrient medium to maintain plant cells in an undifferentiated state for callus formation?

  • A) Correct balance of auxins, cytokinins, and gibberellins
  • B) High sugar concentration
  • C) Only auxins
  • D) Only cytokinins
AI Explanation
Plant cell differentiation and growth are controlled by the balance of plant hormones in the culture medium. Appropriate levels of auxins, cytokinins, and other growth regulators help maintain cells in an undifferentiated callus state.

Q17

How is a cell suspension culture obtained?

  • A) By transferring callus into liquid medium with agitation
  • B) By grinding plant leaves
  • C) By freezing plant cells
  • D) By exposing cells to UV light
AI Explanation
Cell suspension cultures are commonly initiated by transferring friable callus into a liquid nutrient medium. Continuous agitation helps separate cells and small cell aggregates and keeps them suspended.

Q18

A company wants to produce a very high yield of a recombinant vaccine protein in tobacco leaves. They are deciding between nuclear and chloroplast transformation. Which factor, specific to chloroplast transformation, provides the strongest argument for its use in this scenario?

  • A) Chloroplast genes are not subject to gene silencing.
  • B) Chloroplast transformation avoids the use of antibiotic resistance marker genes.
  • C) Chloroplasts are larger and easier to isolate.
  • D) The high copy number of chloroplasts per cell can lead to vastly higher protein accumulation.
AI Explanation
Chloroplast transformation can produce very high levels of recombinant protein because each cell contains many chloroplasts, and each chloroplast can contain multiple copies of the introduced DNA. This high gene dosage can substantially increase protein accumulation.

Q19

A researcher in 1995 wanted to transform a novel ornamental plant species that had never been genetically modified before. Based on the historical development of plant transformation, what was the most significant challenge they likely faced?

  • A) Obtaining permission for field trials
  • B) Isolating the plant's DNA
  • C) Developing a routine transformation protocol for that specific species
  • D) Sequencing the plant's genome
AI Explanation
By 1995, plant transformation methods were established, but their efficiency varied considerably among plant species and genotypes. For a novel ornamental species, developing a reliable species-specific transformation and regeneration protocol would therefore have been a major challenge.
