B. proteome.
C. proteasome.
D. translatome.
E. phenosome.
Which of the following is not part of the P1 lytic cycle?
A. The DNAs are cut from the linear product of rolling circle replication, circularized, and then packaged into phage heads.
B. When P1 DNA enters the cell, it circularizes its genomes using the Cre-lox recombination system.
C. Rolling circle replication occurs, generating many copies of the phage genome as a long linear DNA.

B. lysotoxic phages.
C. parasitic phages.
D. prophages.
E. transducing phages.

B. protease inhibitor and treat all patients in a community simultaneously.
C protease inhibitor that will not be mutated in the aspartate region.
D. protease inhibitor that binds to highly conserved protease sequences.
E. random screening program that tests hundreds of drug candidates.
