Biologists have discovered a new type of RNA-splicing regulation that helps to determine which protein-coding exons will be included in messenger RNA transcripts. RNA splicing is a cellular process ...

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 ...

Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed. There are tens of thousands of lncRNAs ...

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...
