DNA+1+&+2

**1.What is DNA and where is it found?** - DNA = Deoxyribonucleic acid  - Genetic material that carries information  - Transfer to offsprings  - Directs all cells' function - Found in the nucleus

**2.What does it look like (its structure) and what is it made from?** - Appearance: Twisted ladder

- Double helix (Outside): deoxyribose (sugar) + phosphate - Four nitrogen bases (Inside): cytosine(C)+ guanine(G), adenine(A)+ thymine(T) - Base pairs: C+G and A+T - Only C+G pairs up, C and A __//cannot//__ pair up

**Nucleus** = The center of the cell
