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 does DNA do?
• Your DNA determines your PHENOTYPE– Instruction book for your cells
My DNA
• Each instruction is called a GENE• Genes are the recipes for Proteins
• All your genes together is called your GENOME• How your cells read your Genome depends in part

Reading DNA
• MUTATIONS are changes in your GENES that may be inherited– Even small changes in DNA can have big effects– Human DNA is ALL >99% identical!
Career Spotlight!Genetic Counselors
help people figure out if they might pass a disease mutation to their future children

Where is DNA?
• DNA is found in the cells of every living organism– There are different types of cells
• Animal cells
• Plant cells
• Bacteria cells
} DNA found in nucleus (Eukaryotic)
- DNA floating loose (Prokaryotic)
