Question

The DNA of virus A is inserted into the protein coat of virus B. The combination virus is used to infect E. coli. The virus particles produced by the infection are analyzed for DNA and protein. What results would you expect?

A. DNA and protein from B.
B. DNA and protein from A.
C. DNA from A and protein from B.
D. DNA from B and protein from A.

Answer 1

The correct answer is B: DNA and protein from A

Step-by-step explanation:

E.coli Bacterium infected by Bacteriophage.

Phage or Virus has a protein coat and DNA as the source of information or hereditary material.

The phage insert only its DNA in to cell for the production of its progeny or virus particles.

So DNA of virus A will be containing the information of the protein coat including head, tail or tail fibres same as the original DNA virus A. So the progeny formed will be containing DNA and Protein of Virus A.
