Ha - that'll teach me to jump the gun. If I'd waited another 30 seconds or so, I'd have seen your post ;)

I have Matt Ridley's book, Genome .. In the introduction he wrote:
Imagine that the genome is a book.
There are 23 chapters, called chromosomes.
Each chapter contains several thousand stories, called genes.
Each story is made up of paragraphs, called exons, which are interrupted by advertisements called introns.
Each paragraph is made up of words called codons.
Each word is written in letters, called bases.
There are one billion words in the book, which makes it longer than 800 Bibles... This is a gigantic document, an immense book, a recipe of extravagant length, and it all fits inside the microscopic nucleus of a tiny cell that fits easily on the head of a pin.
