COVID-19's ability to mutate into variants and subvariants has baffled researchers. Scientists say this research can help them predict new variants or even produce vaccines for those variants before they arrive.
The findings, published Tuesday in the journal Scientific Reports, have the potential to aid scientists in predicting the emergence of new coronavirus variants and possibly even produce vaccines before those variants arrive.
According to lead researcher Xiaojiang Chen, professor of biological sciences and chemistry at the USC Dornsife College of Letters, Arts and Sciences, the findings could prove vital to curbing the pandemic by helping to prevent new surges in infection caused by new variants. Chen and the USC team reported that they infected human cells with the coronavirus in the lab and then studied changes to the virus' genome as it multiplied, making copies of itself, within the cells.The genetic code sequence of the virus, which is composed of DNA's close cousin RNA, uses four letters to identify component nucleotides: A, C, G, U.
