Utilisateur:Vlad2i/ADN en C

Version française

For many years molecular biologists have been mystified by the fact that very

little of an organism's DNA seems to serve any useful function.

I have solved the mystery.

The reason why only 30% of human DNA performs any useful function is that the

rest of it is comments.

Once we decode a typical human genome, we see that the contents begin as

follows:

===

/* HUMAN_DNA.H

*

* Human Genome

* Version 2.1

*

* (C) God

*/

/* Revision history:

*

* 0000-00-01 00:00 1.0 Adam.

* 0000-00-02 10:00 1.1 Eve.

* 0000-00-03 02:11 1.2 Added penis code to male version. A bit messy --

* will require a rewrite later on to make it neater.

* 0017-03-12 03:14 1.3 Added extra sex drive to male.h; took code from

* elephant-dna.c

* 0145-10-03 16:33 1.4 Removed tail.

* 1115-00-31 17:20 1.5 Shortened forearms, expanded brain case.

* 2091-08-20 13:56 1.6 Opposable thumbs added to hand() routine.

* 2501-04-09 14:04 1.7 Minor cosmetic improvements -- skin colour made

* darker to match my own image.

* 2909-07-12 02:21 1.8 Dentition inadequate; added extra 'wisdom' teeth.

* Must remember to make mouth bigger to compensate.

* 4501-12-31 14:18 1.9 Increase average height.

* 5533-02-12 17:09 2.0 Added gay option, triggered by high population

* density, to try and slow the overpopulation problem.

* 6004-11-04 16:11 2.1 Made forefinger narrower to fit hole in centre of

* CD.
