- 1deoxyribonucleic acid (DNA)• a molecule that carries genetic information in cells
• contains all information necessary to make a complete organism - 2DNA structure• shaped like a double-stranded helix
• composed of one phosphate group, one 5 carbon sugar, one nitrogenous base - 3DNA is made by…1. Enzyme splits
2. Enzymes match As & Ts and Cs & Gs
3. Enzymes continue building along DNA
4. Stops when both strands are an exact copy of each other - 4Four building blocks of DNAAdenine
Thymine
Cytosine
