Dear all,

Wanna Help, Here's an example I'd use to ask my questions regarding how genes are expressed in a plasmid. In the pBR322 below, I’ve noticed that there are two antibiotic resistance markers going in opposite directions. Also, the origin is going in the counter clockwise direction. Could you please let me know now I'm using tetracycline to select for my transformant, how'd the TetR gene be read since it’s on a collision course with the ori?

As I think this is a homework question which you should be thinking about yourself - think about the function of each of the parts you are looking at - the ori is the origin of replication, Tetr is a gene....
