The findings can be beneficial for keeping track of viral evolution in the human population.Advancements in RNA Replication Analysis”The SARS-CoV-2 infection uses RNA, instead of DNA, to save its hereditary information. Our lab has actually long been interested in studying RNA biology, and when SARS-CoV-2 emerged we decided to investigate its process of RNA duplication, which is generally error-prone in RNA infections,” said corresponding author Dr. Christophe Herman, professor of molecular and human genes and of molecular virology and microbiology at Baylor.The researchers desired to follow RNA replication errors since they are important for understanding how the infection progresses, how it alters and adapts as it spreads out in the human population, but existing approaches lacked the precision to detect unusual new SARS-CoV-2 mutations, especially in samples with a low number of viruses, such as those from clients.”Because samples from patients have very few SARS-CoV-2 RNA copies, it is hard to differentiate between the mistakes made by SARS-CoV-2 RNA-dependent RNA polymerase (RdRp), the enzyme that makes copies this infection RNA, and the errors from the other enzymes utilized in the series analysis,” stated Herman, a member of the Dan L Duncan Comprehensive Cancer. “We figured out that, as RdRp is copying one RNA design template or series, it jumps to another template on a neighboring virus and then continues copying the RNA, so the resulting new RNA copy is a mixture of both RNA design templates,” Herman said.
