Versatile enzyme that quickly, accurately synthesizes RNA can also perform reverse transcription
From vaccines and diagnostics to emerging gene-based therapies, RNA molecules are now central to modern medicine. But as ...
The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...
40,000-year-old RNA from permafrost-preserved tissue was recovered from a mammoth specimen known as Yuka. Molecular evidence from Yuka revealed a correction to the original assumption about Yuka’s sex ...
People are still debating whether the mRNA from COVID-19 vaccines remains in the body longer than it should. Some say it lingers and causes harm, others say that idea just doesn’t hold up. A new ...
