Today's Topic:Bacterial Transcription
The basics of the three genetic processes is very similar in all organisms, especially when we look at the elongation steps (adding new nucleic acids or amino acids). The differences usually involve the exact enzymes being used (with prokaryote enzymes generally being smaller), and issues with initiation and termination of the process.
In transcription, we see the greatest differences between bacteria and eukaryotes. For initiation, bacteria do not have the multicomponent complex of initiation factors, and do not use the same promoters. Termination is likewise different. Your task today is to review bacterial transcription, and make sure that you can discuss the initiation and termination of bacterial transcription.
Daily Word: Pribnow Box
This is a new feature to the blog. The daily word is an important word associated with the daily topic. You may need to use it in your blog, but more importantly, it is a word you should get to know.
Daily Challenge: Bacterial Transcription
In your blogs today, you are to discuss the initiation and termination of bacterial transcription (skip elongation). Topics to focus on include: Sigma Factor, Pribnow Box, -10/-35 sequence (also known as hexamers), Rho dependent and Rho independent termination.
