Cells

Life is made out of cells
Cells make copies of themselves
And they make copies of themselves
And they make copies of themselvesDifferent cells have different jobs
But they all have one thing in commonInside 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 livesA 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 youCells are small, too small to see
But together they can make a treeWithin 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 readInside 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 springWhich could also be a spiral staircase
Which could also be a twisted ladder
Or a crazy looking spring, yeah
