moRNA, circRNA, snRNA [How many types of ncRNA do you know? Ep. 4/7]
This week, our journey in the ncRNAs universe brings us back to miRNAs before moving to splicing and the RNAs that make it possible. Let’s get going fellow travellers! 10. microRNA-offset RNA (moRNA) These ~ 20 nt long transcripts are coded in the regions of the pri-miRNA directly flanking the pre-miRNA. They were initially considered…

This week, our journey in the ncRNAs universe brings us into the very heart of the cell, in its nucleus! With a view on the cytoplasm… Let’s get going fellow travellers! 4. small nucleolar RNA (snoRNA) They are ~60-300 nt in length, and are derived from the introns of both protein-coding and non-protein-coding genes. They…

rRNA, tRNA, tsRNA [How many types of ncRNA do you know? Ep. 1/7]
Welcome to the universe of non-coding RNAs! This is a gigantic realm – our cells transcribe over 75% of the genome into RNAs that are never translated! [1, 2] – where the unknown is not just around the proverbial corner, but it often stares you straight in the eyes… Over the next few weeks, I’ll…

How many types of non-coding RNA do you know?
Only 2% of the human genome codes for a protein [1], and yet 75% is transcribed [2]. These non-coding RNAs (ncRNAs) show a mind-boggling heterogeneity of sizes, shapes, origins and functions. Many ncRNAs are essential, either directing or fine-tuning cellular, and a few types are so poorly understood that they may even be junk. I…

Not All Exons Code for a Protein [Common Misconceptions in Genomics, EP. 2]
No, not all exons code for a protein. Far from it. This week’s post will disprove this common misconception by illustrating three core principles in molecular biology. Each one is enough to convince you that not every exon codes for a protein. Together, they will reveal a surprising truth: coding exons are a minority, actually.…
