Scientists find two forms of genetic material chromatin

Biologists have discovered what appear to be fundamental differences in the physical properties of the genetic material known as chromatin. Chromatin packages DNA into cells, and the scientists found the differences between chromatin that packages genes and the chromatin that packages DNA with regulatory or unknown functions. The variation represents a previously unrecognized level of genomic organization and complexity, the scientists report, one that may exist in all cells with nuclei.

Company sequences SARS associated corona virus

At about 4 a.m. this morning, scientists at the BC Cancer Agency’s Canada’s Michael Smith Genome Sciences Centre completed the first publicly available draft sequence for a coronavirus implicated in SARS. “This is a huge step forward in the fight to control the spread of SARS,” says Dr. Caroline Astell, projects leader at the Genome Sciences Centre. Since receiving 1 millionth of a gram of purified viral genetic material from Dr. Frank Plummer at the National Microbiology Lab in Winnipeg, relayed by the BC Centre for Disease Control, scientists at the Genome Sciences Centre have worked around the clock to complete the sequence, using both molecular techniques and state-of-the-art laboratory automation.
