 My question?
   
 1) Can the molecules can form zerox of its own form, or is there some reagent which makes the molecule to make its own image and form no of molecules?
   
Mod Edit - Formatted the subject as a question - please do this to help keep the forum tidy and easy to navigate - thanks

What is Zerox? Do you mean Xerox?

Sorry Sir, I have read your question over and over again and I still do not understand what you mean.

It's a copy of original is known as xerox correct!!!

ok wait ?
 
 Consider a test tube add little bit of solution, and can you make a little bit of solution( having molecules) into larger/no of molecules.

Welcome raghavendra,

TRANSLATION AS I READ IT In Red:
CAN A MOLECULE MAKE (FORM) COPIES (XEROX) OF THEMSELVES (THEIR OWN FORMS), OR IS THERE SOME AGENT (REAGENT)
WHICH MAKES THE MOLECULE DUPLICATE ITSELF AND MAKE MORE OF THE SAME MOLECULES?  (TO MAKE ITS OWN IMAGE AND FORM NO OF THE MOLECULES)


Is this what you mean...? I think this is it!


Full:

I don't know if by using a single molecule you can add something to it to make it duplicate itself.. but I am sure someone on here can tell you..

Crystallization ?

If a crystal is placed in a solution it can trigger more crystals to form from the solution:
 the crystal apparently making more copies of itself.

You could argue that, in the right circumstances, a virus can do this.
In general, self replication is taken as evidence of life.
Viruses, ands prions are borderline cases. Crystalisation is not.

Hmm, I'd take issue with you there, BC (this is rather the area I'm researching in..).
Chemical self-replication is required for life, after a fashion (tho' very little of it is molecules making copies of themselves, it's mainly a lot more complicated than that).

But on a chemical level, that biological self-replication can only occur under suitable chemical conditions and, analogously, a guy called Guiseponne - and co-workers - (I think, I don't have my references on this computer) recently (in the last year) published a paper in which they describe a molecule which self-duplicates under thermodynamic control because the self-duplicating molecule is favoured by self-recognising pair-formation (it's a rather neat piece of work looking at a dynamic combinatorial library).

I'm not much inclined to go into details here, I still haven't really got my lay-persons' explanation of dynamic combinatorial libraries good enough to try doing it in text form!

... in other words, you're saying it's thermodynamically more stable for the molecule to have a pair than not, and assembling the pair molecule is still energetically more feasible compared to not having a pair at all.

Neat.

Do you mean apart from DNA?

What we call a photocopier some other countries call a Xerox machine Chemistry4me. I hate it when that happens, the name of a company replacing the actual name of a product. Like Kleenex. It's the ultimate advertising though

Ah... thank you Madidus_Scientia :)
Yes you're right about the advertising, it is quite annoying to say the least.
So is raghavendra asking about how a photocopier works? :D

No, he's asking if there are molecules intelligent enough to create copies of themselves / reproduce.
