In order to co-ordinate the process, it was also agreed that large-scale sequencing centres would inform the Human Genome Organisation HUGO of any intentions to sequence particular regions of the genome. However, further developments in the field were being held back by the inability to easily read the precise nucleotide sequences of DNA.

After in Middle Age it was imported in Syria to produce with special techniques the " Damascus steel " by the year In fact, he was so ahead of the game that it took three decades for his paper to be taken seriously. The large number of molecular groups made available for binding by each nucleotide component meant that there were numerous alternate ways that the components could combine.
