Chapter 19, Problem 4TYU
Summary Introduction
Introduction: Bacteria are single-celled prokaryotic microorganisms. A bacteriophage is also called as bacterial virus that is formed when a virus infects a bacterium. T2 and T4 are enterobacteria phages that infect and kill E. coli. They are also known as T-even phages because they are double stranded. T-even phages are commonly used as model organisms for various genetic studies. The experiments performed by Hershey and Chase using bacteriophages already proved that DNA is the genetic material of inheritance.

Students have asked these similar questions
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 sample
Which of the statements is TRUE about conjugation?
a)
Plasmid DNA is transferred from a donor (F+) cell
b)
It may only be performed by competent cells
c)
DNA is always integrated into recipient chromosome
d)
It may be specialized or generalized
The induced clones are developed by ________ into the host cell.a) Nuclear transfer b) Gene transfer c) Cell transfer d) Antigen transfer

- In his work with pneumonia-causing bacteria andmice, Griffith found that(A) the protein coat from pathogenic cells wasable to transform nonpathogenic cells.(B) heat-killed pathogenic cells causedpneumonia.(C) some substance from pathogenic cells was transferred tononpathogenic cells, making them pathogenic.(D) the polysaccharide coat of bacteria causedpneumonia.arrow_forwardIn order to determine the genetic material of a T2 phage, Alfred Hershey and Martha Chase conducted experiments using T2 phages that infected bacteria. In one treatment, they grew phages with radioactive sulfur. In another treatment, they grew phages with radioactive phosphorous. They allowed both types of phages to infect bacterial cells. After infection, they found that only bacteria infected with phages grown with radioactive phosphorous showed any radioactivity. Why did they use radioactive sulfur and phosphorous for this experiment? * O Sulfur is part of the DNA molecule but not part of a protein molecule. Sulfur and phosphorous are some of the most reactive molecules and are easily traced. Sulfur and phosphorous are able to survive the centrifuge, a crucial component of the experiment. O Phosphorous is part of the DNA molecule but not part of a protein molecule.arrow_forwardInfluenza vaccines must be changed yearly because the amino acid sequence of the viral proteins change gradually over time.
