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 ...

An expert in the field revealed how genetic testing works, what it means and what steps to take if your family history points to an elevated risk of cancer. Genetic testing, as the name suggests, ...

Thanks to increasingly efficient and affordable gene sequencing technologies, we can now chart our genetic blueprint in unprecedented detail. But what does each gene do? Of the roughly 20,000 genes ...
