Virus: Structure
The coronavirus has the largest genome amongst the RNA viruses. Made of 30,000 nucleotides, the coronaviruses are divided
into three categories. Group one are made of primates, carnivores and animals such as cattle, pigs, and deer while group two
occupies the same animals in group one, in addition to rodents, birds, and animals such as horses, tapirs, and rhinos.
Distinctively group three is only found among birds. In each of these groups, coronaviruses are classified further into host
range, antigenic relationships, and genomic organization.

Researchers from the Michael Smith Genome Sciences Center in Vancouver, British Columbia, and the National Microbiology
Laboratory in Winnipeg, Manitoba were the first to complete the genome sequencing in April 2003. There has been speculation
that the novel coronavirus is part of a new group of coronaviruses as the genome shows that the SARS-CoV is neither mutant
of a coronavirus nor a recombinant between coronaviruses.
"SARS-CoV is apparently maintaining its consensus genotype and seems thus well adapted to the human
host"
As the virus passes through human beings, SARS-CoV is apparently maintaining its consensus genotype and seems thus well
adapted to the human host. However, genetic analysis is able to distinguish between different strains of SARS-CoV, which is
of great value for epidemiological studies and may also have clinical implications.
Research has discovered that as the virus passes through humans, it maintains its original genotype. Yet through genetic
analysis, researchers are able to differentiate strains of SARS-CoV.
