picture focus: The 3 billion-letter 'book of life' provides inspiration for an exhibition

Now that science has begun to draw an accurate picture of the 3 billionletter human genome - the so-called 'book of life' - artists are adding their own interpretations.

Seven artists present Working Drafts: envisioning the human genome, an exhibition at the Wellcome Trust's TwoTen Gallery in London.

Built to Order, by New York artist Chris Habib, presents the genome as an enigmatic puzzle.

The image of textbookstyle chromosomes hides a message. Seen through a red filter, it reveals a computer screen depicting a sequence of the four letters of the DNA code feeding into the umbilical chord of a newborn baby, held by a doctor.

In 99 Genetic Maps of Love, Taiwanese artist Liu Shih-Fen places her own blood and hair alongside illustrations of her 99 genes in a heart pattern to comment on a future where genetics, rather than physical attraction, will play a key role in the dating games of the future.

Spuug van God (Spit of God), by Leon Bloemendaal and Pat-ricia Dekkers, digitally manip-ulates birthmarks to create an obviously artificial pattern of birthmarks.

In Dutch folklore, birthmarks are explained as being the spit of God. Closer inspection of a number of superficially identical ceramic seed-forms in Screen by London artist Amirthi Perera reveals subtle differences in shape and colour. l TwoTen Gallery, 210 Euston Rd, London NW1. Until January 11.
