The Human Genome Project scientists have agreed that whenever they assemble a stretch of DNA that spans 2000 or more letters, they will send the data within 24 hours to public databases. Anyone with access to the Internet can then see and analyze the sequence.
In the spring of 2000, after sequencing the 3 billion letters in the human genome an average of four times, the Human Genome Project had released DNA sequence for 90% of the human genome. This working draft sequence is 99.9% accurate.
