<p>Researchers at Baylor College of Medicine and collaborating institutions developed a new technology called tARC-seq that revealed a genetic mechanism affecting SARS-CoV-2 divergence and enabled the team to calculate SARS-CoV-2’s mutation rate. Using tARC-seq, the researchers also captured new mutations in SARS-CoV-2 in infected cells in the lab that recapitulated observations revealed by worldwide pandemic viral sequencing data. The findings can be useful for monitoring viral evolution in the human population.</p>
