Repressors What are They

Bacteriophages when infecting the Bacteria have to make an important

decision

If Life is bestowed

• Lytic promoters have to be silenced• Repressors come to limelight to do

their job• They Block the promoter’s sites for

lytic pathway then proceed to Lysogeny

• Repressor also binds to DNA at specific sequences

• Found multiple times in genome

Objective is to locate those sites

• By Utilizing• computational tools integrated in BioBIKE,-• A graphical programming interface that enables

biologist to approach complex research questions • Upstream sequences of relevant phages

Testing Time• Apply the same technique to find to

binding sites of some random phages
