What is DNA? • Deoxyribo-Nucleic Acid • Long molecule made of different chemicals called Adenine, Thymine, Guanine, and Cytosine ATGCCTAAGTACCGTATA
What is DNA? • Deoxyribo-Nucleic Acid • Long molecule made of different chemicals called Adenine, Thymine, Guanine, and Cytosine • Shaped like a twisted ladder – Double Helix
What is DNA? • Deoxyribo-Nucleic Acid • Long molecule made of different chemicals called Adenine, Thymine, Guanine, and Cytosine • Shaped like a twisted ladder Career Spotlight! – Double Helix. Geneticists Molecular study the structure of DNA involved in different diseases
How is DNA organized? nucleus chromosome ge ne genome DNA
What does DNA do? • Your DNA determines your PHENOTYPE – Instruction book for your cells MY DNA • How your cells read your Genome(all of your DNA) depends in part on your (and your cells’) environment

Genetic Counselors help people figure out if MUTATIONS they are might changes pass ain your disease mutation to that may be inherited their future children GENES – Even small changes in DNA can have big effects – Human DNA is ALL >99% identical!
Where is DNA? • DNA is found in the cells of every living organism – There are different types of cells • Animal cells DNA found in nucleus (Eukaryotic) • Plant cells • Bacteria cells - DNA floating loose (Prokaryotic) }
What color is DNA?
So how can scientists tell different DNA apart?
What do scientists do with DNA? Scientists use DNA extraction in the lab every day: Ø To find out if a patient has a mutation that might cause a disease Ø To see if one of their model organisms has the gene they want to study Ø We can even use the DNA to change cells by taking DNA from one organism and putting it into another!
What would happen if… Rabbit Fluorescent Jellyfish
Scientists can make all sorts of fluorescent organisms
We can even look at where things are inside of living cells!
Scientists do all sorts of cool things with DNA… What will you do with your DNA? ? ?
