Polyhydroxybutyrate (PHB) granules in prokaryotes serve primarily as a reserve of:
Nitrogen
Phosphorus
Carbon and energy
Sulfur
In the context of producing genetically engineered human insulin, why is the formation of inclusion bodies in E. coli sometimes considered advantageous despite requiring additional processing steps?
A. Inclusion bodies protect insulin from proteolytic degradation within the bacterial cell
B. Inclusion bodies directly facilitate the formation of correct disulfide bonds
C. Inclusion bodies enhance the solubility and secretion of insulin from the bacterial cell
D. Inclusion bodies simplify the purification process by eliminating the need for chromatography
Which of the following is NOT a characteristic of inclusion bodies?
Dense, particulate structures
Composed primarily of protein
Membrane-bound
Often found in diseased or stressed cells
Inclusion bodies are primarily composed of:
Aggregated proteins
Lipids
Carbohydrates
Nucleic acids
In which of the following organisms are inclusion bodies NOT typically observed?
Bacteria
Plant cells
Viruses
Animal cells
Which statement BEST describes the role of inclusion bodies in recombinant protein production?
They prevent proteolysis of the recombinant protein.
They simplify purification but require refolding steps.
They enhance the expression levels of the recombinant protein.
They facilitate secretion of the recombinant protein.
The formation of inclusion bodies is often associated with:
High expression rates of recombinant proteins
Low temperatures during protein synthesis
Abundant chaperone proteins in the cell
Slow protein synthesis rates
Which of the following statements about inclusion bodies is incorrect ?
They are not bound by any membrane
These are involved in ingestion of food particles
They lie free in the cytoplasm
These represent reserve material in cytoplasm
