Homework Answers
Ans.
d. T4 protein and T4 DNA.
Explanation :
As we know the phage insert only its DNA inside the host (Bacteria) and the protein coat remains outside the cell wall of the host.
So, in this case T4 DNA will get inserted inside the host and T2 phage protein will remain outside the host.
Then the T4 DNA will code for the T4 protein not for T2 protein.
Hence, the resulting progeny phages would have T4 protein and T4 DNA.

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...

in the extracellular space.
