News:New research has identified the microRNAs play a key role in combating Covid-19.

Facts:

MicroRNA were first discovered by the scientists in the mid-1990s.They are tiny fragments of RNA genetic sequence produced within the cells.
They are non-coding molecules meaning that they do not translate into protein.
They are part of our line of attack against a viral infection by latching on to the virus’s genetic material(RNA) and cutting it.
However, these MicroRNAs decrease with age due to underlying health conditions.Hence,this may explain why older adults and people with certain health concerns are more likely to die if they contract COVID-19.
