During bacteriophage T7 infection of a single Escherichia coli cell, 1000 bacteriophage particles are released. One of these particles contains a fragment of the E.coli chromosome rather than the T7 chromosome. Will this phage be able to inject its DNA into an E.coli cell, and, if so, how many T7 particles will be produced by this cell?
A) Yes, able to inject DNA. 1000 T7 particles produced.
B) Yes, able to inject DNA. 100 T7 particles produced.
C) Yes, able to inject DNA. 1 T7 particles produced.
D) Yes, able to inject DNA. No T7 particles produced.
E) No, not able to inject DNA. No T7 particles produced.

D.
I had to look it up in the Microbial Genetics/Drug resistance chapter.
This is called a tansducing phage (a phage that has incorporated a piece of bacterial DNA by mistake) It is able to infect another cell, but the products will differ because it creates new combinations of genes in the cell it infects.
