A bacterium is infected with an experimentally constructed bacteriophage composed of the T4 phage protein coat and T2 phage DNA. The new phages produced would have _____
a) T2 protein and T4 DNA
b) T4 protein and T2 DNA
c) T4 protein and T4 DNA
d) T2 protein and T2 DNA
Homework Answers
D is correct answer because phage DNA enter into nucleus and protein get degraded in cytoplasm so phage DNA which enter in nucleus will produce or replicate it's own DNA and also form protein of own type.
So new phage produce T2 protein and T2 DNA.

A permissive bacterial strain is simultaneously infected with
two strains of T4- like phage. One phage strain has the genotype a
-b + , while the other is a +b - . If the map distance between
markers a and b is about 10 map units, what proportion of the
progeny phages are expected to have the genotype a +b +?

Review Each temperate (or lysogenic) bacteriophage (e.g., lambda, 434, P22) encodes its own repressor protein. The repressor binds to six binding sites within the phage genome. These sites can also be bound by a second transcriptional repressor encoded by the phage, called Cro. The pattern of binding of repressor and Cro to these sites determines whether the phage grows lytically or lysogenicaly. Launch the molecular model of the temperate bacteriophage repressor to explore its structure. Then, answer the questions. Launch...

E. coli strain B is doubly infected with two rII mutants of phage T4. 0.1 ml of a 10^6 dilution of the progeny is plated on E. coli B and 0.1 ml of a 10^5 dilution of the progeny is plated on E. coli K. 400 plaques appeared on strain B, 10 on strain K. Calculate the map distance between these two mutations. Please show detailed work to demonstrate where each number comes from and state your reasoning. A. 0.05...

The bacteriophage used in this experiment reproduces by the
lytic cycle. Suppose a similar experiment were conducted with a
bacteriophage that uses the lysogenic cycle. How would the effect
on the infected bacteria MOST likely differ?
A. The bacteriophage would attach to the bacteria and reproduce
in the extracellular space.
B. The bacteriophage would become permanently dormant and
unresponsive to environmental cues for reproduction.
C. The bacteriophage would attach its genes to the bacteria’s
DNA, allowing its genes to be...

The Hershey Chase experiment using radioactively labeled bacteriophage to infect bacteria proved that DNA was the genetic material. If you were reviewing those experimental results, which of the following would provide evidence that DNA was the genetic material? Select all that would apply. a) The DNA was localized in the cytoplasm of the bacterial cell, which is the same site that the bacterial chromosome is located. b) Radioactively labeled viral proteins were only found outside the cell and the viral...

Which two compounds require different amounts of O2 for a complete combustion? (a) ribose and galactose (c) fructose and mannose (b) D-glucose and L-glucose (d) none of these pairs Viruses don’t have ribosomes because: (a) they already carry enough protein to make new virus particles. (b) ribosomes are only needed for DNA synthesis. (c) each infected cell builds new virus capsules from human protein. .

6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...
