I just wanted to thank you for posting your lectures, they have allowed me to actually understand the class because my professor teaches like we have a master in the field and no one understands anything.

is the arginine regulatory pathway similar to that of tryprophan?

Question regarding conjugation, not sure if understood the meaning of conjugation correctly. Conjugation has always to do something with creating pili; pili itself are necessary to transfer bacterial DNA; if a bacterium is F+ this means it has only the property of creating such pili; there has nothing been said about other properties etc. being transfered, correct? Hope you get what I mean. I understood the principle, not sure though if I understood the big picture. Or will be the property of being able to create pili transfered in addition to other information (bacterial DNA etc.)? About transformation: How can one influence the repair system, in order to have more bacteria with the new donor DNA (= which selective media)? Would you also write two or three sentences about transposons?
