Lentiviral delivery of designed shRNA's and the mechanism of RNA interference in mammalian cells. RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression, typically by causing the destruction of specific mRNA molecules. Historically, it was known by other names, including co-suppression, post-transcriptional gene silencing (PTGS), and quelling.
Yuan is the traditional name of the chinese currency. It is the same chinese character that is read yen in japanese and won in Korean. The Renminbi is the renaming of the currency by the Chinese communist when they took over in 1949 meaning people's currency.
Both names are perfectly good, but in slightly different ways. Renminbi is the official name of the currency introduced by the Communist People's Republic of China at the time of its foundation in 1949. It means the people's currency. Yuan is the name of a unit of the renminbi currency. Something may cost one yuan or 10 yuan. It would not be correct to say that it cost 10 renminbi.
