Antibiotic resistance

This is the link to the slideshow we used on antibiotics last week: https://docs.google.com/present/edit?id=0ATFUvVu_WNI_ZGRxdDk3a3hfMTAydnRiOW1kcg&hl=en
Make sure you remember a couple of reasons why Baceria can gain resistance to Antibiotics, and how this occurs.

These are the links to the papers and mark schemes on the AQA website:

Remember that not all the organisms in this segment are Bacteria, but the ones that are need to be specially adapted to their environments.  Horizontal gene transmission helps Bacteria quickly adapt to different conditions such as these. 

Bacterial genetics

This is the link to the slideshow we used today, please email me f this one doesn't work! https://docs.google.com/present/edit?id=0ATFUvVu_WNI_ZGRxdDk3a3hfM2d2ZnR3cGQ1&hl=en&authkey=CNPV_tAN

Remember to make sure you're comfortable with how horizontal transmission occurs, and the advantages of doing so for next lesson.

This is the link to the updated slideshow we used this morning.  Go through the notes again and try the questions at the end.  Tomorrow we will be looking at Bacterial genetics so if you have time reading up on this might be useful.  https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzFUvVu_WNI_NGI2YWM3MjEtMGE2Mi00MzQ3LThjNTAtOGM3YjRjMWZmNTg5&hl=en

I just heard about a talk by James Watson, one of the team who discovered the structure of DNA.  He's giving a talk in London next Wednesday thats being streamed live at this address:
