Question
Chapter 26, Problem 6A
Summary Introduction
Introduction: Any groups of viruses that infect and replicate within the bacteria is referred to as a bacteriophage. They inject their own genetic material into the bacterial cells and use the biological machinery of the bacteria for their reproduction.

Why is it adaptive for a bacterium to not express the genes that encode that lactose utilization proteins when lactose is not available?
a.
Catabolism of lactose in protein transcription needs a lot of energy.
b.
The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve enzymes.
c.
The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve energy.
d.
The reason is conservation of energy for the enzyme.
e.
The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve lactose.

- Why is a webbed plate capable of producing a higher lysate titer (pfu/mL) than a cleared plate? a.) A webbed plate has plaques that have gone through more rounds of replication because the number of host cells did not limit phage replication, creating exponentially more phage particles b.) A webbed plate has no more host available for replication, meaning the plate is full of exponentially higher amounts of phage c.) A cleared plate has less bacteria than a webbed plate, so there are more plaques present d.) A cleared plate contains more phage than a webbed plate because it started with a more concentrated phage samplearrow_forwardwhat event occurs in bacteriophage multiplication that does not occur in animal virus replication?A,B,C,D, or E? a. adsorption to the host cells. b. injection of the viral nucleic acid into the host cell. c. host cell synthesis of viral enzymes and capsid proteins. d. assembly of nucleocapsids. e. replication of viral nucleic acid.arrow_forwardSuppose you have two A-B-type exotoxins, A-B and A-B.
