Miles upon miles of code

Coiled again and again

Unravelled and copied

Replicated and doubled

In the form of four letters

Four molecules

All in an order

Translating into chains of amino acids

Chains that determine our physical traits

What gives us pleasure?

What gives us pain?

Entices joy?

Anger?

Sadness?

Fear?

Excitement?

Contentment?

Chains that dictate

What we look like

Sound like

What color are our eyes?

Is our hair?

Our skin?

How tall are we?

How thin are we?

Do we run cold?

Do we run hot?

These little letters

In strings turned into chains

Physically make us /what/ we are

And those letters are passed on by our parents

But our parents pass on more

They pass on their morals

Their personalities

Their quirks

Their talents

Their humor

Their knowledge

And those things

Are what make us /who/ we are
