12. Where is DNA?DNA is found in the cells of every living organismThere are different types of cellsAnimal cellsPlant cellsBacteria cells} DNA found in nucleus (Eukaryotic)- DNA floating loose (Prokaryotic)
13. What color is DNA?
14. So how can scientists tell different DNA apart?
15. Scientists use DNA extraction in the lab every day:To find out if a patient has a mutation that might cause a diseaseTo see if one of their model organisms has the gene they want to studyWe can even use the DNA to change cells by taking DNA from one organism and putting it into another!What do scientists do with DNA?
16. What would happen if…Fluorescent JellyfishRabbitFluorescent Rabbit !
17. Scientists can make all sorts of fluorescent organisms
18. We can even look at where things are inside of living cells!
19. Scientists do all sorts of cool things with DNA…What will you do with your DNA???
