DNA trip
I am writing to tell you about the exciting opportunity we have been given to take a group of students to the Oxford University Museum of Natural History for a DNA workshop. This event takes place on Friday 1st March 2013, 9.30-3.00 pm.
Students will use PCR to investigate human evolution. It will involve them analysing and comparing their version of a bitter taste receptor gene to their ability to taste. Students will learn about molecular biology techniques by using research-quality equipment. The workshop will be relevant for all Year 12 Biologists as it complements several areas of the course.
Homework-21st feb
1.Watch the ‘wonders of life’ episode- size matters
(great information about how the size of organisms is linked to their surface area to volume ratio)
2. Revise structure of plant cells and leaves for next Thursday
3. Revise DNA structure for workshop on Friday! Hand in your slip if you haven't already so you have a reserve place.

Problem for fish!
Gas exchange is more difficult for fish than for mammals because the concentration of dissolved oxygen in water is less than 1%, compared to 20% in air.
