Which of the following is a bacterial infection?
Typhoid
Malaria
Common cold
Ringworm
Why is Escherichia coli commonly used in the production of genetically engineered human insulin?
Easy to culture and genetically manipulate
Produces insulin naturally
Has a similar genome to humans
Is resistant to antibiotics
Certain bacteria can survive extreme conditions like high salinity, high temperature, or high acidity. This ability is primarily attributed to:
Presence of a nucleus with a distinct nuclear membrane
Possession of membrane-bound organelles like mitochondria
Specialized cell wall structure and unique biochemical adaptations
Their ability to form endospores under all conditions
Which of the following statements accurately differentiates Archaebacteria from Eubacteria?
Archaebacteria have peptidoglycan in their cell walls, while Eubacteria do not.
Archaebacteria lack introns in their genes, while Eubacteria have introns.
Archaebacteria have branched chain lipids in their cell membranes, while Eubacteria have straight chain lipids.
Archaebacteria are sensitive to antibiotics, while Eubacteria are resistant.
The process of nitrogen fixation in cyanobacteria occurs within specialized cells called:
Akinetes
Hormogonia
Heterocysts
Carboxysomes
Which bacterial cell structure plays a crucial role in conjugation, facilitating genetic exchange?
Flagella
Pili
Fimbriae
Capsule
The methanogens, a unique group within Archaebacteria, are characterized by their ability to:
Perform photosynthesis using bacteriochlorophyll
Produce methane as a metabolic byproduct
Fix atmospheric nitrogen in aerobic conditions
Survive extreme high pH environments
The symbiotic relationship in a lichen involves a fungus and which other organism?
Protozoa
Algae or cyanobacteria
Bryophytes
Bacteria
The cell wall of bacteria is primarily composed of:
Peptidoglycan
Chitin
Cellulose
Keratin
