"There really isn't enough genome sequence to be sure," he said.
Before the genome sequences, those comparisons would not have been possible.
The genome sequence was released in the public domain on April 24, 1996.
The main differences between these groups are genome sequence and range of host plants.
On two cases, a complete genome sequence had been obtained.
Following this he played an important role in data collection for and interpretation of the human genome sequence.
The complete genome sequence for a large number of bacterial species is now available.
First, there have been significant changes to the genome sequence between releases.
"Having one complete genome sequence gives you a framework to look for differences."
In 2004 a draft of its genome sequence was published.
