THINGS TO KNOW FOREVER...

Here are a few things that we touched on last Tuesday, and that you should always remember:

- genes have promoters
- transcription does not start at the AUG, and is not stopped by stop codons! (The RNApolymerase does not know the genetic code, it just transcribes until it hits a "transcription termination" signal)
- plasmids can exist as independent "mini-chromosomes" inside bacteria, or they may be integrated into a bacterial chromosome
- plasmids may carry, in addition to all the plasmid genes, some bacterial genes.

FOR THURSDAY AND FRIDAY:
we'll work on prokaryotic gene regulation (two main examples), bring your textbook and problem set#2!

Much more info on prokaryotic gene regulation will be posted in the next couple of days. For more info on the lac operon ...there are links on the right!

Cheers
