  1. Graffiti Using the coloured pen you have been given, visit as many as the posters around the room as you can and write down anything you know about the key terms or diagrams End

  2. DNA What is the job of DNA? Increasing Difficulty • Lesson Learning Outcomes:

  3. Whatisdna? • DNA is amazing! • It can make EXACT copies of itself • It provides instructions for cells to make proteins

  4. Video time! • We are going to extract the DNA from Kiwi Fruit • Watch the video to find out how to do it…

  5. Match the procedure with the reason – write it in next to the correct step

  6. HowsimilarisyourDNAto...? • The person sitting next to you

  7. HowsimilarisyourDNAto...? • 99.7 -99.9%

  8. HowsimilarisyourDNAto...? • Chimpanzee

  9. HowsimilarisyourDNAto...? • 95%

  10. HowsimilarisyourDNAto...? • A banana

  11. HowsimilarisyourDNAto...? • 50%

  12. Whatmakesorganismsdifferent? Organisms differ because they have different genes. • Humans have human genes • Gerbils have gerbil genes • Bananas have (yes, you’ve guessed it) banana genes!

  13. Geneticinformation • The nucleus of living cells contain chromosomes which are made up of a string of genes. • Different genes control the development of different characteristics by issuing instructions to the cell.

  14. WhatisDNA? Chromosomes and their genes are made of a molecule called DNA. DNA stands for deoxyribonucleic acid. The DNA molecule looks like a twisted ladder this spiral shape is called a DOUBLE HELIX Each chromosome is a very long molecule of tightly coiled DNA. DNA molecules carry the code that controls what cells are made of and what they do.

  15. DNABases The double helix ‘ladder’ of a DNA molecule is held together by ‘rungs’ made from pairs of chemicals called bases. There are four types of bases, and they are usually identified by their initials. A C G T

  16. DNABases Base pairs hold the two strands of the DNA helix together. A A T T C C G G It is the sequence of these bases along a DNA molecule that forms the genetic code– it’s that simple!

  17. reflection • Write a tweet (140 characters) to summarise what you know about DNA • It can be your favourite fact or something about where it is stored
