What is DNA
• Deoxyribonucleic acid
• Master copy of hereditary information

Function: DNA must
1. Carry information from one generation to the next.
2. Put that information to work.
3. Be easily copied.

DNA is Simple
• DNA is just a string of nucleotides
• A sugar and a nitrogenous base- just 3 parts

DNA – The Double Helix Model
• DNA twisted double helix “ladder”
• Rails sugar-phosphate backbone
• “Rungs” are nitrogenous bases

4 Bases Always Pair the Same Way
• Adenine-Thymine
• Cytosine-Guanine
