Where it all begins - DNA

DNA, known to biochemistry geeks and molecular biologists as Deoxyribonucleic acid. 

DNA Stores Information

This is the information center of the cell. It contains instructions for the cell that describe how to reproduce, how to communicate, how to maintain itself, how to eat, how to sleep—put simply, what the inputs and outputs of the cell should be.  The DNA performs the same function in a cell that blueprints,  and managers play in  a factory. Blueprints determine how the machinery is put together, and managers  decide which machines and hardware to keep in the factory. DNA provides both functions by determining which proteins are created, and how those proteins are structured. 

Cellular Factories

Think of cells as tiny factories—imagine a chocolate factory—where there are inputs and outputs. 

In a chocolate factory, the inputs are cocoa beans, sugar, milk, maybe some nuts or fruit. Do we need to know the 40,000 character IUPAC name for cocoa to understand this? No! What are the outputs of a chocolate factory? Sweet, melt-in-your-mouth chocolate bars that can potentially be added to s'mores, which can then be input to your cells. The really interesting part of this process (overlooking the delicious chocolate output, of course) is the process inside the factory that turns raw inputs into a useful output. A lot of work went on inside the factory to make bitter cocoa beans into something worth eating. So it is with cells.

Biotechnology - the Alien World Inside

To understand biotechnology, it's best to start by understanding the "bio" part before moving on to the "technology".  

Building Blocks

As diverse as life on earth is, ranging from tiny bacteria to blue whales and aspen clonal colonies, there are simple organizational rules that tie everything together. Life is made up of building blocks that are shared by everything from ancient dinosaurs to paleontologists.

Don't Freak Out

We'll discuss what those building blocks are, so that the "technology" later on will make sense. If you're thinking "I hated third period biology precisely because I didn't get all that biochemistry mumbo jumbo!" don't bail on me now.
