> “'The big question in RNA biology has been whether RNA molecules have a single, constant structure, or whether they can shift between different structures – and what this means for the function of a particular RNA molecule,” says WEHI’s Vincent Corbin.

> "Some viruses use RNA for their genome, including HIV and SARS-CoV2 (the coronavirus that causes COVID-19). In the case of HIV, RNA splicing influences which protein the virus produces – which changes at different stages of the virus’s lifecycle.
> 
> “'Using the HIV genome as a model system, we looked at whether RNA structure influences how HIV’s RNA is spliced,” says Corbin. “We discovered that RNA structure was a critical determinant of RNA splicing in HIV and influenced which viral proteins were produced.

> “'This is the first clear evidence of how RNA structure can control RNA function. The techniques we have developed have opened up a new field of research into the role of RNA structure in regulating the function of cells.'”
