It seems like every year, another new kind of RNA is discovered. We now have a plethora of RNAs, each with their own not-very-informative abbreviations: mRNA, tRNA, rRNA, siRNA, miRNA, piRNA, snoRNA, nanoRNA, not to mention RNAi. It can be hard to keep up with, even for people who are involved in the field. But it is becoming increasingly clear that these various forms of RNA are incredibly important in regulating gene expression.
In this episode of the podcast, we’ll be discussing a group of RNAs called “small RNAs”. Of course, saying “small RNAs” is kind of like saying “large blue whales” or “colorful rainbows.” After all, all RNA is so small that we can never see it even with the most powerful of light microscopes. But even RNA comes in various lengths. While the more famous mRNA is often hundreds or thousands of bases long, the small RNAs are much shorter: usually only around 20-30 bases. Yet despite their short length, these small RNAs have a big impact.
Join us as we discuss several kinds of small RNAs: how they were discovered, why they’re important, and how they work. You can listen to the podcast here:
