Astronomy Picture of the Day -- DNA: The Molecule that Defines You
NASA ^ | August 21, 2012 | (see photo credit)

Explanation: Every living thing on planet Earth is defined by its own molecule -- what's yours? This molecule, called DNA, spans about two meters stretched out but is coiled into every cell in your body. The many copies of DNA that compose you were all copied from one single cell, and your body is continually making new copies. The above ground-breaking animated video depicts the tiny, amazing, bio-molecular machinery that makes these DNA copies. For a fee, it is now possible to find part of all of the code of the DNA molecule that defines you, but lively debates involving ethics may arise regarding whether you or anyone may own, disclose, patent, or copyright it. No one knows if DNA-like molecules will also define life that originates outside of Earth.

Why is NASA calling DNA a part of Astronomy?
To piss me off, I'm guessin'. ;') The terrestrial shots really bug me as well.

Hey, what is Jacob’s Ladder if not the double helix of DNA? ;’)

Since it cannot reproduce without a functioning host cell it isn't possible for a virus to be the first creature; as it would have immediately gone extinct.

Nah... it just waited. Viruses are not exactly alive to begin with, so it's difficult for them to die. There was no need to reproduce until there was something to feed on.

In actuality, no one really knows which was first, as we haven't even resolved the chicken or the egg scenario to begin with.

What cell, or creature, do you think was first ?

We can even find very similar designs in other places.

BTW, which Jacob’s Ladder do you mean ?

The one Jacob dreamed of?

The one King Tut played with?

Or the one that involves an electric arc traveling up a set of almost parallel rods ?

The first one.
