RNA turns genes off!
Right, turning genes off is just one of the things that RNA is
very good at doing. This process is called RNA-interference (RNAi) because the
small RNA interferes with the gene’s mRNA moving from the transcription to
translation processes (see blog 1 for a refresher on this). Today I will
explain one part of RNAi which is how microRNAs (miRNAs) kind of work.
Small RNAs are transcribed that fold back upon themselves in
what is called a hairpin loop structure so you hav...
