Cells

Life is made out of cells

Cells make copies of themselves (copies of themselves)

And they make copies of themselves (and they make copies of themselves)

And they make copies of themselves

Different cells have different jobs

But they all have one thing in common

Inside of every cell is a twisted ladder

A recipe for life called DNA

The directions are written out in the ladder's rungs

Where they can be found

In every cell of everything that lives

A cell knows what it has to do

To grow into some moss or a shrew

Algae or a kangaroo

Bug or a sunflower

Dwight David Eisenhower

A frog, a fish or you

Cells are small, too small to see

But together they can make a tree

Within the cell there's a tiny spiral staircase

That tells the cell just how it's going to grow

The instructions are spelled out in letters

One on every step

In a language that the cell knows how to read

Inside the cell is a tiny double helix

Another fancy word for DNA

Which could also be a spiral staircase

Which could also be a twisted ladder

Which could also be a spring

Which could also be a spiral staircase

Which could also be a twisted ladder

Or a crazy looking spring
