__**Defenition:**__
(deoxyribonucleic acid) Chemical material that makes up chromosomes and genes. p.49 HGD Chapter 3, pp. 49-50

Chromosomes contain DNA strands that pass along genes. DNA are the instructions. Chromosomes are parts that can be put together, or "assembled". They are expressed on the body as genes, or genetic expression. DNA will express 4 different "binding proteins" called 1. TATA binding protein 2. E. Coli lac repressor 3. lucine zipper 4. zif286, or zinc finger.

= __Analogies:__ =

The best analogy for DNA is a blueprint of something, such as a house! DNA contains all of the genetic material that makes you...well you, just like how a blueprint of a house shows the layout of the house since that's what really makes the house a house.

DNA binding proteins are like your friends after a relationship ends. They keep the single DNA from running back into his ex, and keeps the strand from degradation.
