In a study published last week (February 7) in Cell Host & Microbe, researchers annotated three 2019-nCoV genomes and identified both differences and similarities compared with other genomes, including that of severe acute respiratory syndrome (SARS) coronavirus.

“It’s very helpful to know what the genome looks like and what the proteins look like,” says Rachel Roper, a biologist at East Carolina University who was part of the team that first analyzed and sequenced the SARS coronavirus genome in 2003 and did not participate in this study. “It gives us some idea about what protein differences may be that are allowing this virus to be so virulent and transmissible in humans.”
