Bacteria and Bacteriophages
Question:
What is the role of bacteriophages in mapping the bacterial chromosome?
Answer:
They can transduce many genes, aiding in genetic mapping.
Question:
What is the significance of the prophage's small size in transduction?
Answer:
It allows integration into the DNA of other bacteria without direct contact.
,Question:
What is the effect of antibiotic resistance on treatment options?
Answer:
It makes treatment of true infections difficult.
Question:
What is a potential outcome of using last resort antibiotics?
Answer:
They are associated with their own toxicities.
Question:
What is the relationship between antibiotic usage and bacterial mutation?
Answer:
Constant exposure to antibiotics allows bacteria to mutate extensively.
Question:
What is the primary benefit of phage therapy over traditional antibiotics?
Answer:
It may require only one dose and can multiply on its own.
,Question:
What is the primary focus of this module regarding gene expression?
Answer:
To discuss how genes are regulated within bacterial cells.
Question:
What determines the level of gene expression in bacteria?
Answer:
The extracellular environment and conditions for cell growth.
Question:
What happens to lactose-metabolizing genes in the presence of lactose?
Answer:
They are turned on to facilitate lactose metabolism.
Question:
What are inducible enzymes?
Answer:
Enzymes that are activated in response to specific substrates or conditions.
, Question:
What are repressible enzymes?
Answer:
Enzymes that are turned off when specific conditions are met, such as the
presence of a nutrient.
Question:
What is an example of a repressible enzyme system?
Answer:
The genes required for tryptophan synthesis in bacteria.
Question:
What are constitutive enzymes?
Answer:
Enzymes that are produced continuously, regardless of environmental
conditions.
