1. Put these in order of size: Chromosome DNA Nucleus Gene Base Cell Largest Smallest cell nucleus chromosome gene base DNA

2. By the end of the lesson to be successful you: Must * Describe what DNA does. * Carry out a genetic cross to explain how the functioning of organisms relates to the genes they have. Should * Explain how DNA makes proteins. Could * Explain how genes control variation within a species using a simple coded message.

3. Process: How we will learn You will find out about the genetic code and carry out genetic crosses to show how it is possible for characteristics to be passed on to you, from your mother and father. You will learn how genes control the production of proteins and periodically reflect on your progress to demonstrate your learning. Benefits: Why we will learn it Humans have 30 000 genes which carry the codes to control ALL our inherited characteristics. These characteristic range from things like our height, eye colour, even why some people are allergic to kiwi fruit! In future it might be possible for us all to have a copy of a map of all our genes which could tell us if we were likely to develop a particular disease, or to die early!

4. What is your name in DNA code?

5. Task Why are some members of the population allergic to kiwi fruit and others not? Does genetics hold the answer?

6. Translation: Unravelling the Code Use the mini DNA dictionary to translate the sequences into messages for Sample A and Sample B.

7. Coded Messages Read the information sheets about how DNA makes proteins. Use detailed diagrams and sentences to explain the stages involved. (Resources: GCSE Biology pg. 142-142; BFY pg.275) This aspect of genetics is difficult. You will need to show you are an effective participator, discussing issues and seeking resolutions where needed – be resilient & resourceful!
