How Much DNA Codes for Protein?

The human genome: genes and non-coding DNA.
Originally created for DNA Interactive ( http://www.dnai.org ).
TRANSCRIPT: Think of how many letters fit on a single page and now imagine a stack of pages three hundred feet tall. That's how much information is stored in the DNA inside every human cell: the entire human genome. If you sort through the three billion letters that make up the human genome, you find some surprising things. Only about 1% of the three billion letters directly codes for proteins. Of the rest, about 25% make up genes and their regulatory elements. The function of the remaining letters is still unclear. Some of it may be redundant information left over from our evolutionary past.

1.5 to 2 % codes for protein 0.5 to 1 % only transcribed but not translated ( tRNA rRNA snRNA ) 0.5 contains regulatory sequences ( promoter and terminator ) rest appox 97 % remains inactive that includes introns, centromeres and telomeres.
