The human genome programs of NIH and DOE have established the Joint Sequencing Working Group to study and make recommendations on research priorities needed to meet the goal of sequencing 3 billion nucleotides of human DNA within 15 years. Although recent improvements in sequencing technologies are reducing the time and cost required, continued improvement is needed before scientists will be able to sequence the entire genome.
Within 5 years, the Human Genome Project seeks to improve existing methods or develop new ones to lower sequencing cost from the current $3 to $5 per base pair to well below $1. Another 5-year goal is to sequence an aggregate of 10 Mbp of human DNA (and 30 Mbp from model organisms) in large, continuous stretches.
To date, complete DNA sequences have been determined for some viruses, of which the largest sequenced so far is the cytomegalovirus containing 240 kbp. Investigators are attempting to sequence bacterial genomes that contain about 4.5 Mbp. Although many short stretches (an aggregate of nearly 7 Mbp) of human DNA have been sequenced, the complete sequence of the human genome will total some 500 times that amount. Projects will be initiated to develop and assess strategies and technologies for sequencing whole chromosomes and for reducing the cost.
To begin formulating strategies for achieving these goals for sequencing, the working group met on May 10 in Herndon, Virginia.

The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome. See Timeline for more HGP history.
Published from 1989 until 2002, this newsletter facilitated HGP communication, helped prevent duplication of research effort, and informed persons interested in genome research.
