The process of gene expression involves DNA transcription into mRNA and translation of mRNA into protein.
During transcription, genetic message in DNA is encoded into mRNA. The encoded messages are then translated into their respective amino acids during the process of translation.
<em>Hence, if a virus uses its genome as mRNA, the next stage will be to translate the messages in the mRNA into amino acids. Translation rate is expected to be measurable.</em>
This is easy, CO2 is (Carbon Dioxide) a main cause of air pollution. We put it in the air every day when we drive cars or vehicles. And from wildfires and volcanoes, but they rarely erupt now.
